If you want, you can make your own tornado and watch it all day. What you need is two 2-Liter bottles, duck tape, and a washer (or tornado tube). Here's what you do:
Fill one of the bottles two-thirds full of water
Place the metal washer or twist the ‘tornado tube’ over the opening of the bottle
Turn the second bottle upside down and place it on the washer or twist it on the ‘tornado tube’
Use the duct tape to fasten the two containers and the metal washer together. Make sure to tape tightly to make sure that no water will leak out when you turn the bottle over. If you use the ‘tornado tube’, just twist together tightly.
Turn the tornado maker, so that the bottle with the water is on top. Swirl the bottle in a circular motion. A tornado will form in the top bottle as the water rushes into the bottom bottle.
*If you want to get creative, you can also use food coloring to make the tornado have a color and glitter to represent debris.
