I'm building an air gun

Yo that's really cool. It would probably be cooler if I knew what I was looking at. How do air guns work?

It's basically just an air tank and a solenoid valve. The barrel is just right to shoot one inch rubber balls.

That's pretty cool. Have you recorded the muzzle velocity?
If you don't have a device to measure it, you can record it in slow mo on your phone (assuming your phone supports its) from the side, firing past a clearly marked board with strips exactly a centimetre thick. You can then review the footage, record how many frames it took for the projectile to pass a certain number of strips, and then knowing the number of frames per second, calculate its velocity.
*insert cliché inspirational quote here*

I plan on shooting it across some stripes, but I haven't got a chance to yet.
I did end up with some steel ball bearings to shoot out of it though. This is an old washing machine at 80psi.
