As a kid, I had heard the "fact" that everyone in my age bracket accepted: "a nickel, left in a glass of Coca Cola, will eventually dissolve." I decided to test the claim. Without mentioning it to my parents, of course. Those people always stepped in at the last minute of my experiments, usually just before I lit the fuse. The result after a month of rigorous study: urban fact become urban myth. The nickel did not dissolve. But left in my bedroom closet, it did attract a pretty impressive trail of ants, presumably there to steal my nickel. Some time later, I took the "pyramid challenge". This one had yours truly, the budding scientist, constructing a pyramid of cardboard, which aligned to true north, would sharpen a dull razor blade. Result: It did not. So I moved on to another of the pyramid claims, that it would preserve meat, eliminating the need for refrigeration. Remember that trail of ants coming after my nickel ....? en.wikipedia.org/wiki/Pyramid_powerAnyone here as a young person, attempt to set the scientific world on its ear. Perpetual motion machine, perhaps? |

It was a penny, not a nickel. When I was a kid I dissolved several pennies in Coke. With coin mints having removed the precious metals from coins a long time ago, it might no longer work with a penny either.

As to the perpetual motion machine all that is required is a buttered slice of bread and a household cat. Buttered bread always lands butter side down and cats always land on their feet. Strap a slice of buttered bread onto a cat's back, butter side up and drop the cat. It will rotate forever and never land.

No wonder the Las Vegas casinos would not allow glasses of Coke near the penny slot machines back in the 1950's. And I understand that during his stint at The Sands, Sammy Davis Junior accidentally left his glass eye in a water tumbler filled with the stuff overnight, with disastrous results. |

For some time now I’ve had trouble, on and off, with gravity and inertia. I’ve got the broken bones to verify it. “o)

At 8 years old I pretty much knew the X-ray glasses weren't going to work -- so I never committed my hard earned allowance to further science in that area.
I will confess to spending several solitary afternoons overlooking the pool in our apartment complex imagining the theoretical possibilities.

The kinetic energy required for the tied bikini top on the female from 2B to unravel, based on a dive at the deep end of the pool, from the springboard ............ |

A friend and I pondered whether or not you could "catch" light if you trapped it inside a cube with mirrored inside walls. The theory was that it would continue to reflect from one side to the other for eternity. Problem was, we could never look inside to see whether the light was still in there.

I did an ESP project in junior high. I had a friend of mine memorize the cards to make it look like he had ESP. Theory proven!!!
I think I actually got 3rd place for that lame project.

The kinetic energy required for the tied bikini top on the female from 2B to unravel, based on a dive at the deep end of the pool, from the springboard ............ From numerous days at the local pool, it was the bottoms that were ripped off on the dive. It was fun to wave the said bottoms in the air and tease the poor female. Unfortunately it only happened once to each, and a few learned from watching. Actually it only happened once and it was my GF at the time. |
