Cranky Contraptions

Our local library hosted a class recently, so I took Gamma and Delta there. The class was called Cranky Contraptions and was actually run by a nearby museum / science center.

Here is Delta’s result – a geyser:

They’re called Cranky Contraptions because the design is based on a crankshaft, and you turn the crank to make the kinetic sculpture move.

Here’s a different view of the geyser:

And for one in motion, here’s a GIF of Gamma’s marshmallow roasting contraption:

It was a fun class, and the boys liked it more than they thought they would. We were about the last ones there. So I recommend it as a project. If you want to try this yourself, it’s easy enough. Try this link for more ideas on cranky contraptions.

Half of it he burns in the fire; over this half he eats meat, he roasts a roast, and is satisfied. He also warms himself and says, “Aha! I am warm, I have seen the fire.”
