This is a really cool experiment that requires almost no time at all. It is really fun and interesting to see the fire travel down the bottle. But, we are using fire, and safety needs to be our number one priority. Do this experiment in a well ventilated area, keep flammable items clear from the experiment, and keep a source of water nearby.
Step 1: Things You Need
The items you need for this experiment are as follows:
- Denatured Alcohol
- Clean, empty plastic bottle
Denatured Alcohol is highly flammable and potentially toxic, read the warnings before usage.
Step 2: Preparing the Bottle
Pour a small amount of the alcohol into the plastic bottle, you don't need that much, just about 1/4 inch from the bottom. Screw on the lid to the bottle, then shake vigorously, making sure to coat the entire inside of the bottle.When you are done, pour the Denatured Alcohol into a safe place, like down the toilet or outside in the grass.
Step 3: Light It Up
Before you light the bottle, clean any of the Denatured Alcohol from the he area, this is a safety precaution. Now strike a match, and touch it to the rim of the bottle. A wave of fire should travel down the bottle. Your bottle might have melted a bit at the top, and this looks really cool, but be careful, the bottle is still hot.
