This is a great trick, and it's pretty cool. If you do it right, you won't get burned, but it is fire, so there is always a chance. So, if you want to play with fire, impress your friends, or just know how it works, read on.
Step 1: Materials
- 100% cotton (from t-shirt)
- 100% cotton thread
- Rubbing alcohol (70% or 90%(hotter)), or lighter fluid (VERY HOT)
- Sewing Needle
- Matches/ lighter
Step 2: How does it work?
The basic idea is that the cotton doesn't burn because the fuel (rubbing alcohol) burns instead. What happens is the heat turns the alcohol into gas (it evaporates), and the gas burns, causing heat, which makes more gas to burn.
Cotton burns, but doesn't melt. Other materials that have plastic in them will melt and burn you.
Why doesn't it burn you?
It doesn't burn you if you keep it moving because the lower part of the flame is cool enough to handle for a short amount of time in one place. However, the top part of the flame is hotter and more likely to burn you.
