2- 2 litter plastic bottles (clean and empty)
1-inch metal washer
#1: Fill one of the bottles about 2/3 way full of water. May add food coloring to give your tornado color or glitter for debris.
#2: Place the metal washer over the opening of the bottle
#3: Use duct tape to faster the two containers and the metal washer together. Make sure to make the tape tight so no water leaks out.
#4: Turn the bottle with water over so that it is on top. Swirl the bottle in a circular motion. A tornado will form as the water rushes from the top bottle to the bottom bottle.
