One of the ways that Tinkering School stays interesting for me is that we don’t overly pre-test the ideas - that way the kids participate in the experimentation. So, it took us two sessions to get the kinks worked out of the boat formula, but once we got it working, the kids lined up to make boats.

We had to put up a sign-up sheet about halfway through the morning on Saturday. From then on we were booked up for the rest of both days.

Check out Julie’s action shots on Flickr. We’ll get some video up in the next day or so.

It’s fast approaching, and there is still much to do (wash bottles, build race tank, label tools, collect set dressing, write handouts, draw diagrams, calibrate race timer…). But last night, I did get one thing done; I washed juice bottles.
