Description
The activity will show the students how a tornado looks up close in miniature size.
– Fill one of the bottles two-thirds full of water.
– Add food coloring and a dash of glitter.
– Use duct tape to fasten the two containers together.
– Make sure to tape tightly so that no water leaks out when you turn the bottles over.
– Flip the bottles so that the bottle with the water is on top. Swirl the bottle in a circular motion.
– This will create a vortex and a tornado will form in the top bottle as the water rushes into the bottom bottle.
