Tornadoes are formed when hot-humid air collides with cold-dry air. This is what scientists call an updraft. The spinning of the tornado is due to the sharp change of speed in the direction that the wind is moving. The constant spinning is called the vortex. Tornadoes are a very powerful force that cause natural disasters all over the globe because of how powerful they are. It is hard to get an up close look of what exactly is happening in a tornado. But today, we will be creating our very own tornado in a jar. It’s very easy and only takes about ten minutes to create.
