Homemade backpack flamethrower

FlametitleBrady writes "What you see is a homemade backpack flamethrower. I initially got interested after finding this page showing another guy's plans on making one. I tried twice to make the main tank out of PVC, but for some reason the PVC just did not want to hold more than 50 PSI without leaking (the first one actually exploded at about 75 PSI). So I went the more expensive but safer route by using a metal tank. Also, with a metal tank you can use gasoline ($2.50/gallon) instead of denatured alcohol ($10/gallon) as the combustible liquid because gasoline eats PVC, so if I went the PVC route I'd have to use denatured alcohol."

Flamethrowers are soooooo 1940-1945....

But yeah, it is cool somehow (or should I say HOT?).
