This will be a Fett style Jetpack based on measurements I got from thedentedhelmet scaled down to a shorter person.
Styrofoam - Free coolers from Craigslist
Foam Board - Free from Craigslist (apologizies to any Shaft fans but I am cutting up a piece with a movie poster printed on it)
Top and Bottom of the fuel cells - Plastic eggs that were filled with candy from the dollar store
Rocket - so far its just a paper towel tube
Center (hump) - a cut up 3 liter bottle.
Exhaust/Jet Nozzles - the top cones from Renuzit air fresheners from the dollar store.http://i215.photobucket.com/albums/cc51/swgskalex/JP2.jpghttp://i215.photobucket.com/albums/cc51/swgskalex/JP1.jpg
My side goal of this is too make it as cheaply as possible.
