Science Club Experiment Suggestions - also posted in Education

[TwoShanks]

I'm hoping to start up a club for year 10 and 11 students (14-16 year old) at my school which would involve more interesting experiments than those conventionally done at school. The difficulty is that I need some experiments or demonstrations to do with these kids.

My current list, which has gained some interest, is:

Organ dissection (Heart, lungs, eyes, possibly others)
Nitrogen Tri-Iodide (Contact explosive-this one is doubtful due to danger)
Bed of nails
Time fountain (UV strobe with fluorescent water droplets)
Homeopathy
Dowsing/Ouija boards
Horoscopes
Cold Reading
Spoon Bending
and that's about it.

I need more, preferably impressive to watch/fun to do, but safe enough for a school lab. Any suggestions?

If you are interested in some more 'soft' science stuff, this is a great set of social psychology class demonstrations. (http://jonathan.mueller.faculty.noctrl.edu/crow/activities.htm) Many of them would make fun experiments. Starting with the ones under 'The Self' - a lot of the earlier ones aren't what you are looking for.
