Confetti Cannon / Konfetti Kanone

How to build your own confetti cannon:

1. Print this model, standing up on the smaller side, should not need supports. If you need a brim, try an inner brim only. We want to avoid sharp edges where the ballon will go. I added a small lip, so to avoid needing a brim.
2. Cut a ballon ⅓ from the open part.
3. Stretch it over the smaller side and secure it with tape.
4. Fill the cannon with confetti.
5. Pull the ballon, 3-2-1 LET GO!
6. Goto 4.

We build this with a toilet roll today, which also works. But is very flimsy (if you are in a hurry, try that), so I designed this and made it look a bit more cannonny. Also i hope the kids will have a bit more grip on it then. 

Happy new year or whatever you are celebrating with this.
