Bug's "Tornado" science project

Bug was looking for a science project with Tornados to go along with the state he was studying- Ben told him that the "tornado in a bottle" (where you fill a jar with water, put in a marble and twirl it around, and it makes a tornado) wasn't enough of a project. So he found this project instead. While Doodle and I were at the Zoo- Ben and Bug were preparing a tornado! The modified the experiment and made it easier and cheaper- using glass from picture frames that were around the house and a vacuum (as opposed to the plexiglass and a bathroom exhaust fan)- the top and bottom are scrap pieces of wood with lines cut in them for the glass to rest in.

Here is the tornado! Looks pretty amazing!

There's a bowl of hot water in the bottom with some dry ice dropped in. The
kids were amazed at the properties for Dry Ice- So Ben made them some "Sprite" my making lemonade- and dropping some dry ice in it- they were all fascinated as it bubbled and steamed everywhere.
