Attach lid and fire away.
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...
