• a large can or bucket
• a plastic bag
• a large rubber band, or a roll of duct tape

1. Ask an adult to help you cut a hole in the bottom of the bucket, about the size of a CD or DVD.
2. Cover the top of the bucket with the plastic bag. Stretch the bag tightly, like the head of a drum. Use the rubber band or tape to hold the plastic in place.
3. Pound on the plastic "drum", and feel the air puff out of the hole.
4. Practice aiming the air cannon at different objects, and blowing puffs of air at them.
