Tornado in a Bottle

You can create your own tornado in a bottle. All you need is two bottles, a tube to connect the bottles, and some water. When you whirl the liquid in the top bottle, it creates a vortex as it drains into the bottom bottle. That’s because as the water flows down, air must flow up, creating a spiraling tornado. You can even add glitter, food dye, or lamp oil to the bottle to make the tornado even cooler! Check it out here >
