We started today's class at the Foundation, as usual. We spent about 40 minutes building rockets. Each kid made 2 to 5 versions. Then we walked the block over to Riverfront Park. They have a nice big lawn area there were we set up the rocket launcher and rolled out a 100 ft. tape measure. After that I pretty much held the launcher at the angle the kids wanted to try, and blew up the 2-liter bottle over and over and over again! I was a little winded after an hour of this activity!
In case you don't know what I'm talking about now, I suppose I should describe the launcher in a little more detail. Basically it's a PVC pipe with a bicycle inner tube attached to one end. The other end of the inner tube is attached around the neck of an empty 2-liter pop bottle. The kids put their rocket on the free end of the pipe, and then stomp down on the 2-liter bottle. The air gets pushed out of the bottle, up the inner tube and pipe and propels their rocket into the air. Some of the rockets traveled over 130 ft across the lawn!
It was pretty simple for me (I was grateful to have the help of two assistants - shout out to my mom and Dani - as well as the parent of one of the students who stuck around and impressed (and challenged) the kids with his far-flying rocket!) The weather was nice, the kids had fun. No one got hit in the eye. Good week, good summer. I'm glad to be finished, but wouldn't mind doing it again if the opportunity arises.
Stayed tuned in September for my return to the world of subbing!
