I volunteered to give a ~ 50 min presentation on "science magic" to
~20-30 high school students in about 3 weeks and was hoping some pe=
here had some favorites they might like to share. Hopefully the dem=os
will be 1) entertaining, 2) educational, 3) low budget and 4) not t=oo
difficult to perform. I plan to present a brief explanation of eachsame
feat, but no really involved derivations or anything like that.
Some current ideas include
1) bed of nails (I'd have to build one soon)
2) string tied above & below a heavy weight (slow pull breaks top
string, quick tug breaks bottom string.
3) cabbage juice pH indicator.
4) juggling on a force plate (showing that the average force is the=
whether juggling or not)a
5) Bernoulli ping pong ball suspended on a stream of air.
6) cooling & crushing a container full of steam
Do these sound reasonable? Any other ideas? Links to website with
similar info? I don't think these will take 10 min each, so I need =
few more!_______________________________________________
Thanks in advance.
