Boom! The classic potato gun harnesses the combustion of flammable vapor. Show us your combustion spud gun and discuss fuels, ratios, safety, ignition systems, tools, and more.
New test, but that the PAL is assembled and glued.
The barrel is made of PVC-P with holes D14mm, covered with transparent polycarbonate.
The rupture disc is aluminum, 7 sheets total, approximately 0.2mm, I did in snitch because I've never used aluminum sheets ... too thick? not enough?
The noise was terrible, a gunshot!
