How to Make a Tornado in a Jar
This tornado in a jar experiment is crazy simple to put together, and it's so fun to watch!
Fill the jar with water, leaving about 1" space at the top.
Add a generous squirt of dish soap (approx. 1 teaspoon) and one or two drops of food colouring.
Screw the lid back on securely and swirl it around to mix it.
Swirl the jar in a circular motion as fast as you can until tornadoes form.
If you're having trouble with too many bubbles, try adding 1 teaspoon of vinegar and using a spoon to scoop out the bubbles on the top.
