If you are only making a one-bottle tornado, you can use a plastic water bottle or a clear glass canning jar. [3] X Research source If you are making a larger two-bottle tornado, try using a pair of two-liter soda bottles. Try experimenting with more or less water. Record whether the amount of water has any effect on the size and speed of the tornado.
Don’t try to use other cleaning products like bleach or non-liquid soap. Do not use laundry detergent: it is designed to interact differently with water than dish soap. [5] X Research source Try experimenting the amount of dish-washing soap, or the brand of dish-washing soap. See if a particular brand works better than another, or if more or less soap makes a difference.
Why is it spinning?[8] X Research source Is the tornado spinning clockwise or counterclockwise? How does the glitter interact with the tornado?
