Hey, we never said it was a “functioning” jetpack. Function is overrated anyway. The creative process? Now that’s where the real entertainment lays.

A much cheaper alternative to buying a real pack just to complete your Rocketeer costume.
Instructables user ModMischief has a step-by-step how-to over at the source link. It’s a relatively simple process and the finished product is definitely worthy of a Halloween costume if nothing else.
