In this incredible science experiment I'll show you how to make an indoor tornado in a few easy steps! I'll show you how to make a giant tornado out of dry ice and show you how to do it in a few easy steps using only dry ice a fan and warm water! I bought a large industrial fan and a lot of dry ice and flipped the fan upside so that the suction will pull the "smoke" carbon dioxide upwards and create a vortex!
Guva Juice tried to make an indoor tornado and Steve Spanger did it as well as a random college class made whats probably the world's largest indoor tornado! Links below...Here's how to do it - Put the dry ice in warm water and you'll see alot of vapor form...then put the fan upside down on top of it and you'll see the suction start to make a tornado from the carbon dioxide.
