How to Make an Air Cannon


  • 1 paper/ plastic drinking cup (bottom of cup should be smaller than the rim)
  • 1 deflated balloon
  • Scissors
  • Tape (optional)
  • Drill (optional)











  1. Use scissors to cut out the bottom of your paper cup. This hole should be about the size of a 50 cent coin or bigger. If you are using a plastic cup, get an adult to help you to drill a hole of the same size.6
  2. Stretch out the balloon a little by blowing into it and letting it out the air twice. Cut the tip of the balloon using scissors.7
  3. Spread out the balloon over the rim of your cup. You may want to use tape to make the balloon more secure by taping the edges of the balloon.       21
  4. Your air cannon is set! Pinch the middle of the stretched out balloon, pull back and let go.
