In this video I team up the The Proper People to make blow huge fireballs and spin steel wool in an abandoned mine! All you need to make these fireballs is cornstarch. Just grab a hand full and blow it onto a flame. This is probably the safest way to blow fire...Just remember to blow hard enough to keep the fireball away from your face! I souped up this experiment by loading a whole box of cornstarch into a air cannon. I pumped it up to 60psi and triggered the valve which sends air exploding through the bottom of the pile or the cornstarch turning it into a huge dust cloud. A torch at the base of the dust cloud ignites it once it reaches the correct fuel/air ratio. You can use flour, sawdust, or coffee creamer also for this experiment, It would probably taste better also!
