My friend Baz believed that a large truck travelling along a road would stop dead for a tiny fraction of a second each time a fly hit the windscreen (that's a "windshield" for you folks from the US of A). He was aged 33 when he let that one slip!
My dad told me to work out how to achieve perpetual motion and so I used to try and for ages he just said I must be doing it wrong until one day I realised.
When I was young, I used to occasionally get paranoid that gravity would suddenly start working in reverse. When I thought about this I would always try and make sure that there was a roof over me, just in case, cos I didnt want to fall into space forever.
i used to think that if you disconnected your speakers while playing music, the noise would build up inside the wires like water at a dam, and when you plugged them back in the built up sound would all come out at once like a flood.
When I found out that Neutrinos passed through anything, I thought that they caused people to itch when they passed through them.
My sisters once told me that if you tripped, and then had something sudden happen to attract your attention, you would float. They told me that this was because we are so convinced that the Laws of Gravity are true that therefore they work. But when you are suddenly distracted, you forget about the Laws of Gravity and thus you float. Lets just say that jumping off of stools and ladders and having your sisters throw things at you is not a good idea...
(I believed this for several days until my Dad told me that they got it from some books by Douglas Adams.)
When I was little, I saw a science show on t.v. that explained about how splitting atoms would make nuclear explosions etc...etc...etc... So I believed if a person just broke something or tore something in half it would cause atoms to split and blow apart the planet.
i used to belive that if you talked into a bubble while blowing into it it would say what you said before
One of my first days in preschool I stepped on a crack and one of my classmates freaked out saying that I just broke my mom's back. When my mom picked me up I apologized profusely but instead of setting me straight she replied, "I was wondering why my back hurt all day." I avoided cracks for years until one day I got mad at my mom and stomped on a crack repeatedly. When it didn't work I assumed that it only worked with some cracks and continued avoiding cracks for an embarrassingly long time.
I used to believe that echos were actually the sound going completely around the world and coming back to you.
when i was i child i used to believe that everyday there was a new sun in the sky.
When I was learning to ride my bike, I was absolutley convinced that I had to balance on it perfectly still BEFORE I started pedaling. Took me a while to get the hang of that!
I used to believe that I invented the X Y coordinate system.
I thought that infrared was actually "info-red" because it gives you more info about the thing your looking at than normal vision (I wasn't sure what the red part meant tho)
I used to think that little bakers lived in the toaster who baked the bread and pushed it back up.
I used to think that filling a plastic bag with air took away the gravity inside.
I spent many hours at my grandmothers testing this theory with a plastic sandwich bag and a ten cent coin.
I always got confused when I watched movies with pepole jumping of trains or cars that was moving. Thats because I thought that if I just stepped of I woudld immediatley stand still, not faling and hurt myself. Because it was the cars or train that was moving, I just sat there...
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.
I used to believe that heat and cold were two separate energy forces. It was only actually "cold" when the temperature was below zero, whereas seemingly cold temperatures above zero merely indicated a lack of heat.
I remember seeing the sun set and it didn't look all that far away, really. I also imagined it as being about the size of my wading pool. I was hoping for the day the sun would come down right in our yard. I wanted to go touch it.
