Washing machine vs. Air cannon (concrete projectile) 

At last, new material!
I filled my promise and I fired washing machine 2 kg projectile concrete.
Does not spin anymore..
Projectile: 2070 g (~4.56 lbs) concrete-filled cardboard tube
Pressure: ~9 Bar (~130 psi).
Washing machine drum rotated at 1200 rpm. (Now 0 rpm)
Unfortunately, I could not shoot again today, because the horses did not like sound of the cannon. =/
