You don't have a camera capable of high speed by any chance, I bet those cans compressing would look great in slow motion :) good job!

nice job on the crushing but the can split still needs some work, im surpirezed you guys can get a better slice than me since i was using a blunt edge when you guys use much sharper objects...

Load it so the bottom of the can hits first. Part of the split can is due to the can getting a shot of compressed air inside the can on launch.

I can tell from the cement pattern on the rim that it was launched top first.

I never tried any low pressure shots. I'll have to try some to compare notes.

Nice wrap around on the hoe. Nice shot.

Edit, Just for grins I thought I would test the marshmallow cannon again. After the success with the tennis ball and the long barrel, I decided to try the long barrel with pop cans. The lack of enough flow is very obvious.

3 cans. The two on the outside were launched from the 7 foot barrel. I'm not impressed. The middle can was launched from the 3 foot barrel. Much better except my aim was too high.

Another try with the 3 foot barrel worked well. I am going to have to compare the 3 foot and 7 foot barrels on the larger launcher. It may be interesting.
MysterySplat.JPG
Using the 1 inch barrel, I shot a mystery item at my target. Anyone care to guess what it was?

My target was the handle of this propane tank. I did not use a sharp edge for those shots. The mystery splat was shot at the side of the tank.
