Sounds like an idea for the jump in place competition at the BEAM games as
well.

you'd use on SMA. If you can figure it out, great, but typicaly, you
need the current to drive throught the whole contracting process, and
then when released, it stretches. Good luck!

Devin I always just used refrigerator magnets to magnetize my screw drivers,
remember just drag the magnet in one direction only with the same polrzation.
that's all there is to it. Must say I have never seen magnetic screw drivers
to buy
Just my $2.50

photopoppers or bodies for aquavores to inclose the circuitry.
(sorry for the bad spelling if their is any)
