Science experiments lesson 7: Balloon rocket · Set 813 · 40 questions

What you do (Push back, move forward): 1. Thread the string through the straw and tie it tightly between two chairs. 2. Blow up the balloon (not too much) and pinch its neck shut. 3. Tape the balloon to the straw, neck pointing backward. 4. Let go, measure how far it goes, and keep it away from faces.
