Tennis Ball Cannon

Made as part of a team-building contest at my company.

Some stills:

not bad for accuracy!

 The tennis ball is top center left, its shadow is just left of target! At 25 m distance, the precision was 3m in length and 1m in width. The pieces of bark and stones mark the "hits".

multi-launch

 Immediate post-launch: Elsa wanted to launch as many as possible simultaneously, we got up to 4!

Four in the air

Piston at full post-launch extension.

Looking down the mouth of a loaded cannon - see how much I trust Maya.

A 2 -minute video compilation

Home Made Cannon

All videos taken with a Flip video camera, and the slides are simply still captures from the video. I couldn't have captured the photos without a video camera, and the Flip has astoundingly good resolution!
