This rocket man jet pack is made out of:
2 2 liter pop bottles
1 silver table cloth from dollar store ( I had it)
1 Seatbelt like strap with locking ends ( I had this)
I wrapped the pop bottles in the mylan silver table cloth and secured with clear tape. I configured the strap and cut it to fit using hot glue to secure the jetpack in place. Finally the fire is colored streamers secured with hot glue to the open bottle cap upside down. He loves It!
