Jet Pack Boy Costume

This is my son Ethan wearing his optical illusion jet pack boy costume. Probably the most key points to his costume are the fake legs and the flames. The flames are created by sewing strips of fabric on a skirt. I also glued some to the bottom of the jet pack. The best way I have found to make fake legs is to wrap a subjects leg in Saran wrap then wrap with strips of duct tape. Use strips instead of one continuous piece so that it doesn't become too tight. Cut a line down the leg to remove the tape. It doesn't matter where you cut it because you just tape it back up with duct tape. Fill with plastic grocery bags. For the buttocks section I used two balloons taped to the top of my fake legs. I wrap tape around them then popped them and again filled with plastic bags. This was the most realistic and lightest (very important when dealing with young kids) way I could find.
