what you needtwo coins of the same valuewhat you doplace one coin in each hand, as shown in the pretty poor diagrams.left hand.[diagram=291_0]right hand.[diagram=292_0]yes, they are the worst diagrams you have ever seen....any way. the coin in your right hand should be in the middle of your palm, and the coin in your left hand needs to be close to your thumb..this is obvious in the diagrams!now turn your hands so they are palm down, where are the coins?*****can anyone do better diagrams? if you can please feel free to edit mine...pleasewhats happeningrotational mechanicsWhen you turn your hands over you're rotating them around their centre point, which is near the middle of your palm. The coin in the middle of your hand will just drop straight down, so it'll stay under that hand. But the coin out near your thumb gets rotated around the centre point of your hand, and that flicks it over under your other hand.
Posted by: Make it Lady Insert QuoteOh Paul I love this one. I once convinced a year 7 pupil that one of the past teachers had really been killed and we had found the bones to examine. The bones were plastic prop.s but this poor kid was convinced it was all real. All these kitchen experiments work so much better if you weave a little story around them. But take care of young gullible children.
What about writing a letter saying that you are being black=mailed by the victim and you think you have found a way to stop it. (In other words MURDER THEM!!!) If you write with an ink pen you can do chromatography on a sample of ink that came from the letter and different types of ink that came from the suspects pens. They have to find out who's pen wrote the letter.
You can also use a fizzy drink as fuel of vinegar and bi-carbonate of soda. The latter launches quicker so you have to be very quick.Note: The film canister must have an internal seal or it won't work.
I tried it earlier with an aspirin bottle (a plastic 1) and it worked. [B)]
