science

My grandfather told all kids that when the lights blinked, it was because "a fish went through the dam". We believed if, not sure for how long. I do know my Mom was in college before she found out otherwise!

I used to believe that when tieing knots in rope that the more normal knots you "stacked" on top of each other the stronger the knot would be

When I was young I used to fear that when somebody takes a photo of me I would go inside the camera and cannot see my parents forever. For this reason I used to cry when anybody tries to take a snap of me

when i was about 6 we did a project at school about space and our teacher told us about 'black holes' that were big enough to suck in the earth and squash it. I was terrified and for several weeks i used to pray every night that the earth wouldn't get swallowed. Then i think i forgot about it!

i used to believe that if you were in a falling elevator, you could just jump at the last minute before it crashed at the bottom of the lift shaft, thus reversing your direction while the lift crashed around you. Then you'd land (still inside the mangled lift wreckage) as if you were landing after a normal jump. Genius.

I went for a short time as a child beleiving that I should be able to support myself on something I was holding up: take a metal pole, hold it behind your back horizontally, crouch slightly as if sitting on it then try to lift your feet off the ground. Even though I tried and failed, I was convinced I just wasn't doing it right.

It doesn't fit the vehicle categories, but I think this one's pretty good:
When we were kids a friend of mine thought a ten centimeter long propeller driven ship I had in my bathtub was exactly as fast as the ferrys from Norway to Denmark, because it was a copy of one of them. I disagreed even though I was two years younger. We got into a really long and tiresome argument about it, and I don't think we ever managed to agree. It's been years since I saw him, but if I run into him maybe I should ask if he still thinks it could be the case. He's 34 now.

when i was little, i used to believe that there was a band inside every speaker and the more expensive the speakers, the better the band was.

Like others, I also reduced elements to water, and everything else. I thought all liquids had water, except mercury, and, strangely enough, milk. There was a milk mystique in my house.

I was convinced that I could invent a machine that would pressurize wood, but denying it oxygen, it would not burn, but melt. I'm still not convinced it's impossible. :-)

I couldn't figure out how bombs worked. First I believed that planes could drop giant stones crushing whole cities. But I soon realised planes couldn't carry stones that size, and then thought they could drop a big fireball in the middle of a city, and then divide in to smaller fireballs rolling through all streets and burning everything up on its way. I must have been around 4

I used to think that you could show something to the person on the other end o the phone line by holding the receiver up to the object. I still remember trying to show my grandmother a present I got for Christmas. I held the receiver to the present and said "See, Gramma?"

When I was about 4, I believed that if you scrub a vinyl record hard enough, long enough, with enough soap, you could erase what was on it and record your own songs there instead. I was never quite able to do this successfully, (this was before recordable CD's, or any CD's actually), but I did render several vinyl records completely unplayable.

We had a fridge with an unmarked switch inside. After I had flipped the switch a few times (turned off the defrost settings? Turned off the fridge? I dont know...) my sister told me that flipping the switch turns the neighbors house upside down. (!) I believed her until I was about 5, at which point I performed an experiment (flipped the switch and ran outside), and was very, very relieved to find the neighbor's house right-side-up.

My father had me beleving that in every electronic device, such as televisions and keypads. Lived a little Japanese man who controlled everything in that particular device. And made things happen depending on what button you pressed.

When I first phoned a call centre, they told me that I was put on hold. Then some music like Greensleeves was played into my ear. I thought that the person on the other end got out her recorder and played it to me down the phone!
