VORTEX CANNON!!!!!!!

Aim:
To make a vortex cannon.
Equipment:

1. Bucket 
2. Tape 
3. Rubbish Bag 
4. Cups (Optional)

Methods:

We are not making an ordinary vortex cannon. Instead of making one out of a cardboard box we made one out of a bucket. We had a bucket and we cut a hole at the bottom(To any size you want).Then you put a rubbish bag on the hole covering it. Then next you will tape it together.

Results:

My group tried to shoot the cups with the cannon from 3 meters. The cups just wiggled a little bit. But the cup tower didn't fall over.

Discussion: 

Next time I would make the hole smaller.
