Why doesn't my potato cannon work?
Today, I finally got to test my spud gun. I loaded it up with a plug of potato, sprayed in one second of hairspray, twisted the cap shut, and pressed the barbecue ignitor. I heard the ignitor work, but nothing happened. I tried this again and again, using different potatoes, cleaning the cannon, and checking the sparker. Every time I did it, it didn't work. I followed the instructions step by step from Backyard Ballistics, but I used ABS instead of PVC. I also used a barbecue ignitor instead of a lantern ignitor. I used all ABS parts, with the right cement for ABS, so I don't know what went wrong. Could it be my hairspray? I bought a $1 can, which seemed a little strange, because all the other cans were at least five dollars. Is cheap hairspray made with different chemicals? I believe the hairspray brand I used was called "White Rain", but I could be completely making that up.
