Create Your Own Tornado!
When you created your tornado, did you ask yourself these questions? Well, we’ve got some answers for you!
- In which direction does your vortex move?
- Did you notice that your vortex moved counter-clockwise? That’s because of something called the Coriolis Effect. Since Texas is located in the Northern Hemisphere, above the equator, your vortex will most likely move counterclockwise because of the way the earth turns. If you lived below the equator your vortex would turn clockwise.
- What would make it go faster? Slower? Your vortex (tornado) went faster if you gave your bottle a twist. That makes the vortex skinnier, helping the force of gravity pull it out of the hole.
- To make your vortex slower you would have wanted to leave the bottle completely alone so that you did not create any movement that would have helped gravity help the vortex.
- How is it different in the middle than at the edges? Did you notice how your vortex was tighter in the middle than at the edges? That’s because more pressure gets put on the water in the middle.
