Making Cork Boats with Colourful Shape Sails

A friend gave me a big bag of corks. The most obvious thing to do was play around in a big tub of water. We watched them float. We laughed at them pop up through the surface when we pushed them under. We blew them over the surface and had cork boat races.

Then we talked about how they looked like little boats and how we could make them look more like boats. "Let's make some sails" was the joyous suggestion.

So we chose six shapes.

We picked six corks and found some cocktail sticks.

And we watched them float, tip and capsize.

Then we made a giant sail which, to my surprise, worked!

And then the corks were under attack!
