Many of you have reported being burned, scarred, hurt etc. I've made these, and tested them with different fluids. I will show you in detail how to make these, explain how they work, and share my notes on the best kind of flammable fluid to use.
This trick is really fun to perform, and a great way to reuse an old t-shirt. It is still fire, though, so be careful! If you want to know the science behind it, check out step two.
Step 1: Supplies
100% cotton t-shirt or fabric
100% cotton thread - make sure it's thick enough to hold the ball of cotton together, but not so thick that it won't fit through your needle
Needle with eye big enough to fit the thread you are using
Some kind of flammable liquid (details on this in step 8)
Not much, huh? Make sure everything is all cotton. See the next step for reasons why. Skip to step 3 to get straight to work.
