Yesterday my son checked out a book about weather and wanted to perform an activity in the book. It required drilling a hole in the caps of two bottles, gluing them together by the caps (after having filled one with water) and when you turn it over and the water runs from one bottle to another...voila! A vortex!
In theory that is.
My son got a lesson in drilling holes. Fabulous.
Then came the 'gluing together' part...guess what? No super glue. Not even duct tape.
So I used masking tape out of desperation. I KNOW.
Then the big reveal....which didn't work because the holes he drilled were slightly too small and the water dripped pitifully through.
So we discussed air pressure instead and showed how when you squeezed one bottle, the compression forced the water into the other bottle.
As we were cleaning up, hubby expressed his disappointment in the failure of our experiment.
"I think it went okay," I said. "He learned how to use a drill! Besides, we watched the Decorah Eagle Cam this afternoon and saw a chick hatch, so we have science covered anyway."
"Everything is a lesson with you, isn't it?" hubby muttered on his way out to the trash can.
Yes. Yes, its is.
