Nobody better pinch me on St.Patricks day for not wearing any green!! Bored on spring break? looking for a project? Look no further! In this video I make and demonstrate how I made a green flamethrower from a squirt gun, antifreeze (methanol), and Roach killer (Boric Acid). I hacked this squirt gun flamethrower together for only $10! The ratio of methanol/boric acid :12oz of methanol 1 teaspoon of boric acid. I do this so you don't have to :).. or so your parents wont yell at you for melting
