Experiment: How To Build A Tornado
Add enough water to fill ¾ of the glass jar.
Put in some food coloring, as well as a teaspoon of dishwashing detergent.
Place the lid back on the jar and shake it hard for 20 seconds
Twist the jar hard.
The liquid should form a funnel that resembles a real tornado. The vortex’s body will even lengthen and shorten, just like the real storm.
