This craft is super simple, fun and introduces the basics of propulsion. All you need is a piece of paper, 1 pipe cleaner a straw and tape. Draw and cut out a jet pack wearing character that is about 4-5 inches high. Bend a 2 inch piece of pipe cleaner into a zig zag shape and tape it on the pack of the jet pack character so that about 1 inch of pipe cleaner will fit into the straw. Place the paper character on the straw and blow on the other end to launch the character into the air. You’ll have fun experimenting with design improvements and with launching the character at different angles!
