This stuff is great man. used to self massage stiff muscles and improve flexibility.
need one for my back.
aching probably due to poor posture when sitting.
and i sit way too much.

had a parachute competition for our aerolab.
tooks us 2 wks to finalise everything.
our team was the only radical design which looks like a spider.
everyone else's was basically a very well fortified box.
but then again its more practical.
first throw we made 4 out of 9 eggs.
but apparently the 5 that din make it only had very small cracks.
second throw was 6/6 which netted us 36 points cos perfect score = square the number of eggs carried.
third one we got over confident added 8.
do or die cos another group made all ten.
end up we only managed 3.

Visited the Science Center last week for a short workshop.
supposed to make sth known as a sound automata.
basically its a small engine and u use it wif lego blocks to make as much sounds as possible.
so here we hung all sort of crap and a turning thingy in the middle.
apparently the things were to heavy for the engine.
so not much noise....
