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?

We used to make those too. We called them tennis ball canons. You pretty much described the whole thing. Make a big tube from a bunch of cans taped together and put a hole in the bottom one. Squirt lighter fluid into the hole, put your tennis ball in the other side, and light the lighter fluid through the hole.
