This "cannon" is actually disguising a golf umbrella, hidden in the ramrod. The cannon is made out of cardboard, with a little foam for structural support, plus the candy cane spokes. The cannon has a remotely triggered CO2 canister hooked to a solenoid valve to launch Christmas ornament on command. Link to the construction album.
It's hard to tell dimensions from the picture, and I don't have a banana. But it is 90" from the tip of the barrel to the end of the trail.
Our family has been doing this for over 35+ years. Here's a few links to years past constructions:
2009: Hedge Trimmers. Bonus: Decoy umbrella, a broom (to replace the one he accidentally ran over with his car that Fall), wrapped like the umbrella gift: http://imgur.com/WZxFzyX
Edit: We built a remotely triggered CO2 canister rig inside the barrel to launch a Christmas ornament: Link
Edit2: The umbrella is a promotional gift you get this time of year from Aramis, which my mom buys for my grandfather for his birthday at the end of November.

Next year, get them a cannon. Wrap it exactly the same as this year.
They'll never suspect it.
