Putt-Putt Boats

We made some putt-putt boats while studying the Industrial Revolution and the steam engine. They were fun to make and we loved the putt-putt sound they make.


We were expecting a successful launch at a friend's neighborhood lake.  However, we didn't take into account the sprinklers going off and the wind! 

 We tried again in our bathtub and they worked!

Here's a video to hear the cool sound they make.
