The Parachute

We've decided a couple things about parachutes.

1) We're going to have one. And..
2) We're going to make our own.

I picked up some orange nylon fabric for the chute. My brother Brian found a web page with instructions on calculating the shape of the pieces for the chute (http://www.cit.griffith.edu.au/~anthony/kites/parafauna/chute_design/ - and we found out people like to put parachutes on stuffed bears apparently) and together we made it in about three hours. It looks great and works perfectly.

We decided to make it about 36" in diameter. I think this may have been a bit large but we'll see how fast it descends with the weight of the final payload attached.
