Step 4Attach Lid and annoy others.
If you cut the hole, try and keep the hole to about half the total diameter of the lid (to make better rings).
To fire:
Pinch and strech latex. A puff of air will travel a meter or more. This puff is not incredibly powerful, but can be felt. The TWUNK sound as the cannon is fired will annoy parents/spouses/co-workers within three minutes.
Add smoke and you can make smoke rings. I imagine some creative type could come up with way of shooting smells...
Happy Building
