• 10 litre bucket
• plastic bag
• tape
• scissors or sturdy knife (Caution: Ask an adult to help you use these tools)
• Pyramid of cups (25 cups)

Method

1. Collect equipment.

2.Cut a Large round hole on the bottom of the bucket (Flat hand length)

5. Fill your vortex with smoke and watch as it makes smoke rings.

6. Record the time the smoke ring leaves the vortex to when it knocks down the cup.

7. Stand with foot then step back away from the bucket.

8. We’ll make the cannon but not put in the smoke cause we have to make the pyrimid
