My Uncle in the 1970s taught me how to make a cannon that went boom with just tin cans, electrical tape and Rossignol fluid, taped together and holes in the first few cans. Made a very loud boom. How was this made?

All of the cans had both ends cutout of them except one…the bottom can. The end of the tube was sealed by that end of the can. On the side of the can just an inch or so from the end you put a hole large enough to squirt in the lighter fluid. I remember some kids shaking the tube to try and get the lighter fluid throughout the tube and not just in the end, but I never noticed that helped.
