This is why I feel a bit of guilt from laughing at Pickle Girl and Cotton Ball Lady from The Maury Show but I still laugh becuase they can never scare me inside a studio like that. Their missing sun and rain. Maury just couldn't cut it.
I have a confession to make. I have Iridophobia (fear of rainbows) I have all my life. Only real rainbows though. Pictures and ones painted on walls only make me cringe and put me in discomfort. I used to be scared of pictures of rainbows when I was younger. I had my share of being made fun of when at school a rainbow showed up and I freaked out and cried. Than kids were drawing rainbows on their hands and flashing them at me. They screamed "Rainbow! Rainbow! Rainbow girl!"
I had an experience as a child when I saw double rainbows on the front lawn. They seemed very close (around 20 feet) so it frightened me but I was still scared of them but seeing them that close a curious fear turned into a phobia.
Now-a-days I keep it under control. It's not so bad but if that close double rainbow thing happens again I would probably go into shock.
I can look at them from inside. They don't scare me when I'm inside but they do if I'm outside especially if I'm by myself I will panic and look for shelter like a bomb is gonna fall.
I'm scared of them becuase there mysterious and weird. The way they re-appear and evaporate. When I little their was the same rainbow in the same spot in our back yard that would keep re-spawning in the same area every time the weather would go into sun and rain. I remember getting an adrenalin rush from spraying rainbows with a spray bottle. Another weird thing was I would quickly touch them while the spray lasted. Than I'd cry and rub my hands on the deck railing...but...later on when I sprayed near the railing I saw rainbow hand prints! I'm not fucking kidding. I remember this shit when it happened. I knew the difference between reality and imagination.
Their HUGE. They look like their watching you. The way their a big massive arc stretching over entire cities.
It's not just rainbows. Things in the sky make me become submissive. I can't sleep under the stars knowing that their giant balls of fire bigger than our sun and more powerful than any nuclear weapon on earth. I also fear Jupiter and Saturn.
This video freaks me out but truly amazes me. It blows my mind.

We have lots of double rainbows where I live, so this might not be a good place for you to visit.
If a scientific explanation will help, then here's a pretty good explanation of double rainbows:
http://www.straightdope.com/columns/read/2279/what-causes-double-rainbows
While on vacation recently our family saw a double rainbow. How do these occur? Why did the second faint rainbow (which was on top of the first) have the opposite color sequence?

Ah, rainbows – those will-o'-the-wisps of ethereal beauty, made possible only by a full lineup of optics phenomena. Let's run down the list:
1. Refraction. When a ray of sunlight strikes a raindrop, the ray refracts, or bends, at the point where it passes out of the air and into the water of the drop. The angle of the bend is determined by (a) the intrinsic light-transmitting properties of air and water (every transparent substance has its own individual index of refraction) and (b) the angle at which the ray strikes the surface of the spherical droplet – whether, e.g., it hits the drop squarely or strikes a glancing blow off to one side.
2. Dispersion. Meanwhile, the drop is acting as a prism, splitting the white light of the ray into its component colors by refracting the different wavelengths at different angles: red wavelengths bend a certain amount, orange wavelengths a slightly different amount, and so on.
3. Internal reflection. Most of the light striking the raindrop passes straight through it and out the far side, but some of it reflects off the rear interior surface of the drop and is sent in some new direction. The ratio of light transmitted to light reflected is, once again, a function of the angle at which the ray hits the surface.
4. Refraction and dispersion, part 2. When the reflected light exits the drop and re-enters the air, it's refracted and dispersed a second time.
Light rays emitted by the sun are effectively parallel when they reach the earth, and raindrops are effectively all the same shape. So when sunlight shines into a sky full of raindrops, it's encountering millions of tiny, very similar spherical prisms and interacting with each in pretty much the same way: each produces a basically identical pattern of refracted, dispersed, reflected, and re-refracted light in a spectrum of colors. The reflected red light is at its greatest intensity at an angle of 42 degrees from the direction of the sun's rays, while the violet light has maximum intensity at 40 degrees. When you face a rainy sky with the sun at your back you see a ring of red light, forming the outer edge of the rainbow, at 42 degrees from the direction of the sunlight, a violet ring at 40 degrees forming its inner edge, and all the other colors of the spectrum in between. The rainbow is entirely an optical illusion; it changes its apparent position in the sky as you change your vantage point, meaning that no two people are ever seeing a rainbow the same way (and explaining why that pot of gold is so elusive). Also, because the light forming the rainbow is reflected at angles of 40 to 42 degrees, for the most part rainbows are seen only during the hours around sunrise and sunset: if the sun is higher than 42 degrees in the sky the rainbow reflected by the raindrops will be below the horizon for an observer at ground level. You get better viewing at greater altitude, and it's possible to see complete circular rainbows from an airplane.
Now, about double rainbows: What's happening here is that the ray of sunlight bounces twice off the back interior surface of the raindrop before re-emerging into the air. The second reflection inverts the order of the colors – the secondary violet band forms at 54 degrees, the red band at 50.5 degrees – so the secondary rainbow appears above the primary one, with red on the inner edge and violet on the outer. Because the twice-reflected light has had two chances to be transmitted out the back of the raindrop rather than reflected back toward the observer, the secondary bow is much fainter than the primary and frequently cannot be seen at all; it's typical for a secondary rainbow to be visible only at certain points along the arc.
If the light is strong enough to remain visible after being reflected three times inside the raindrop, an even fainter tertiary rainbow can sometimes be seen (at least in part) above the secondary one, with the red back on the outside and the violet on the inside. And rumor has it that it's occasionally possible to see a quadruple rainbow.
Nitpickers will ask: What about diffraction? Doesn't it play a role here too? All I have to say is (a) yes, diffraction – a quantum phenomenon where light waves cancel each other out or amplify one another – sometimes figures in rainbow formation, if the raindrops are small enough, in which case (b) all bets are off – you might get smaller rainbows inside the main bow, you might get rainbows with the red in the middle – but (c) no way am I going to work out the math for this. If you're desperate to know this kind of stuff, well, that's why they invented physics grad programs.

I used to be afraid of bad weather. The tornado drills back in elementary school were a little too melodramatic, like air raid drills. From then on I was afraid of weather that might spawn tornados. Here's how I dealt with it... Years later, I had a fucking tornado rip through the front yard and then go rip the roof off a neighbor's house. (Well, I didn't have it rip through the front yard. The front yard just happened to be in its path.) It was night and I didn't know what was going on at the time. The Weather Radio went off with a tornado warning, so I knew one was in the area, just not how close. Apparently, real close. We went outside afterward and saw the mess it left. Cleared that fear right up. My crazy bitch of an aunt was there. She was even more afraid of weather, and it was worth it to see her scared shitless. I could barely hear the Weather Radio because she wouldn't shut up. Maybe that's why I didn't realize how close it was.

I'm still afraid of them, not because they will injure me, but because I may get something I love fall and flush down he toilet never to see it again. I'm super careful with my belongings near those types of toilets. The toilets that clean your butt and vagina with a water stream I used in Japan and Korea were awesome. Not a spot on the toilet paper.

I'm scared of the garbage disposals that Americans have in their kitchens. I'm amazed that there aren't a lot more people walking around with missing fingers or hands.
I'm a little scared of spiders. Just like Americans have tornado drills at school and sometimes grow up scared of bad weather, we used to have a spider expert come around every year and teach us about the spiders that could kill us and what to do when we got bitten. A great way to produce a generation of kids with arachnophobia. It didn't always have the desired effect, one of my friends used to carry a deadly redback around in a matchbox, and take it out on a regular basis to tease it and make it try to bite him. Nobody did that with funnel web spiders, we were all well scared of those.
Stairs, I really don't like them.
My daughter is terrified of crabs. Mostly the little ones like soldier crabs.

We lost a few knives to them.
Those things are worse than useless though. You basically can't put anything through them that you couldn't
send down the drain anyhow, without it gunking the machinery up eventually.
-
I saw a horror movie once where someone had their hand forced down a garbage disposal. It was pretty grisly. I bet that has happened in real life.
We have dishwashers here but I've never lived in a place that's had one.
-
We had one when I was a teenager. But it had a safety mechanism where you can't stick your hand down it. I'm sure if you tried to put a safety mechanism on a garbage disposal in the US someone would say something silly starting with "garbage disposals don't kill people....".
I remember on the TV series "Heroes" where that cute cheerleader who married the enormous Russian boxer (Hayden Panettierre, can't be bothered to look up the correct spelling) dropped her ring down a garbage disposal and tried to grab it. It made a mess of her hand, but she had super self-healing (luckily). I nearly did the same thing once in the US, caught myself just in time.

Whenever I hear people talking about 'deadly black widow spiders' (by that, I mean the genus Latrodectus in general, any of the true widows), it's true the bite is HORRENDOUS, and it hurts like a motherfucker, all over, there isn't a muscle in your body that doesn't get pushed passed the point of screaming, and towards begging for death, but it isn't likely to actually kill anyone, unless they are already sick, very young or very old and go untreated, a healthy person is very unlikely to die in this day and age from the venom, whilst alpha-latrotoxin is on a weight for weight basis, considerably more lethal than that of at least some of the cobra snakes, they have tiny, tiny fangs and not very much OF it. And besides, given the invention of antisera raised against Latrodectus venom (which is probably polyvalent among any of the true widow spider genus), there is very little reason anyone ought to die from a bite, suffer, yes, been there, done that, but die? no.
And the primary defense instinct is to run and hide, it's only in extremis when they will bite a human, generally if undetected in clothing or bedding and pressed against the skin. Or, as I found out, at least in Latrodectus geometricus, brown widow, the females seem to get PISSY when they've just laid eggs.
Even a country isolated and unable to administer antisera against the venom of Latros, you'd have to be pretty badly fucked already to be at serious risk.
They don't really GET pissed off, most Araneomorph spiders don't seem to have that bad of a temperament, even Sicariius spp. have been reported as relatively docile in captivity (if one DOES bite you, you are SO fucked, they are related to the recluse spiders, but the spiders are MUCH bigger, perhaps the size of a red-kneed tarantula, but a lot flatter of build, and their venom is similarly based on sphingomyelinase-D, and acts as a flesh-rotting cytotoxin, and quite likely the deadliest spider known to science in terms of venom weight lethal dosage, and definitely nastier, at least if one recovers from most spider bites, there aren't likely to be permanent sequelae, but necrotizing toxins that destroy flesh, are just nasty.)
It's the big Mygalomorphs that seem to be the pissy ones (Araneomorph and Mygalomorph refer to fang orientation, the former, exemplified by widows, recluse spiders, orb-weavers have jaws that come together like a pair of sideways-oriented pincers, the latter have generally larger builds, and downward-stabbing fangs that are oriented like a pair of downwards-thrusting daggers, like funnelwebs (Atrax, Hadronyche and....fuckin' buggrit...Al, Ren, MOSW, what was that recently discovered third tribe of Hexathelidae funnelwebs in oz? discovered a few years ago, not too long back, can't for the LIFE of me recall the damn family name, and no, I do NOT mean Missulena) Very aboriginal-linguistically leaning binomial name for the family. And same sort of fang configuration as the Mesothelids, very, very primitive, non-venomous sister group of spiders, perhaps dating back to when spider and scorpion lineages first diverged, given they are the only group to retain segmentation of the abdomen, although reduced to a series of plates.
MOST araneomorph spiders tend either to be small, or fairly docile, or else non-hazardous to humans, main exceptions being Phoneutria (brazillian wandering spider), which have both a potentially deadly bite and a near legendary mental-case temper, and the Sicariids (Loxosceles, Sicarius) with their virulently necrotic venom, the chilean recluse, L.laeta is apparently particularly toxic, and fatalities have occurred after bites from L.laeta, whilst their Sicarius relatives, are thought to considerably outdo the native ozzy spiders in terms of sheer 'you are royally fucked' if you get bitten, AFAIK no antivenom is available, they are not noted to be severely bad-tempered.
(Note-recent reclassification of many of the genus Sicarius sensu stricto, has resulted in the removal to a separate genus, Hexopthalma, which appears to be the sub-group containing large Sicariids with highly potent necrotizing venom.
-
I've several times seen Brazilian wandering spiders classified as the most deadly spider in the world, and Sydney funnel webs classified as the second deadliest spider in the world. Sydney funnel webs tend to be very aggressive but they make a lot of dry bites because they drip their venom onto their fangs rather than inject. I was reading about a woman recently bitten on the chest by a Sydney funnel web spider, and it wasn't a dry bite. Even with an ambulance called straight away and plenty of antivenom available and administered, they nearly lost her. But you're pretty safe in general, just get a pressure bandage on it and get to a hospital asap.
Here is an article on the new one they found in Tasmania:

Sicariid venom is MUCH nastier stuff. There IS an antivenin raised against Loxosceles venom (recluse), which ought to be polyvalent against Sicariid venoms in general.
BUT...it's made in brazil, and one needs to administer it within 12 hours, for a bite by the six-eyed sand crab spiders until recently classified as Sicarius, unlike most spider venoms, which rely on a neurotoxic venom, often ion-channel modulators that shift the desensitisation kinetics, or fuck with the resting potential for voltage-gated sodium channels, forcing the voltage-gated Na+ channels to depolarize at their natural resting voltage, for example, and locking them in an open-conductance state, causing parasympathetic hyperstimulation, as with Atrax/Hadronyche in delta-atraxotoxin, versutoxin, and missulenatoxin from the mouse spiders works in the same way.
These spiders, the Sicarius spp. (I'm using the old nomenclature, as it was only changed VERY recently to reassign S.hahnii and others to a third family within the Sicariid clade), the antivenom for a recluse bite needs to be given rapidly, these buggers live out in the middle of nowhere, usually, although they seem to be ending up in the pet trade too, apparently not too aggressive, but extremely hard to spot in a tank, as they camouflage themselves with sand and dig in, and they are lightening quick if they feel like it.
People aren't too likely to be bitten, but if it DOES happen, it really isn't pretty. Basically flays the victim alive, whilst causing their red blood cells to lyse and muscle tissue to break down, trashing the kidneys in the process, and progressing to DIC, the venom nature, is very similar to recluse venom, but the concentration of the flesh-rotting sphingomyelinase-D is orders of magnitude above what any Loxosceles species produces, and they are bigger spiders and can deliver a lot more of it.
Systemic involvement in recluse bites (I.e haemolysis, rhabdomyolysis etc.) is pretty damn rare in the case of most Loxosceles, although L.laeta at least, has caused fatalities, but where a recluse is pretty small, Sicarius spp. are about the size of a man's palm, known instances of human bites are rare, but out of two cases, one guy died, other one lost an arm.
At least with neurotoxic spiders, if it's treated, or if it doesn't need treatment, but the cytolytic venom is downright ugly stuff and will leave hideous messes behind that last a lifetime.
And I remembered the name....Illawarra, thats the bugger.
