Awesome video. I love how excited people get when you demonstrate a decent spudgun to them for the first time.

No Behemoth soundtrack though. :cry:

Yeah it's weird how you can build something simple and fun and people love it, yet you build a hybrid and they lose interest before you've got the fuel measured out :wink:

Yesterday we were at the same place shooting tennis balls straight up and some little girls were running around trying to catch them, people jogging by coming over to check it out, people playing tennis stopping play and taking a look. Today we had some guys playing basketball stopping to come watch and a kid and his mum also coming over to look.

Though my brother said he could hear the cannon very clearly from our house (150m away), so I do appreciate the neighbourhood putting up with the noise.
