Tornado!
It has been a few months since Brennan and I did a science project. This has been the case mostly because of his fascination with trains, specifically traction rods on trains. I am thinking that the trains fascination may run its course pretty soon but hopefully not before we take him on his birthday party which is all about trains. Enough on trains for now … I’ll post birthday pictures soon.
An upcoming fascination of Brennan’s is Tornados, which I agree are really cool to look at but not too cool in real life for those that are unfortunate to be in one. He has memorized the Fujita scale but hasnt quite latched on to the concept that the size of tornado doesnt dictate the strength of the wind. That’ll be a next step. Here is a quick video of it in action:
To make a long design / science discussion short, the box is cut so that there are slits in the sides which make the tornado funnel spin as a motor on top sucks the dry ice smoke up. Email me at dana@danaedwards.com if youwant to know more about the physics of how it works. Here are a couple of photos of it in action:
We had a blast making it and hope to show it off to the grandparents for Spaghetti Night tonight and Thanksgiving Dinner soon!
