Today is a free blog day so I decided to do some extra research on the putt putt boat project. Most noticeable in its appearance in the movie "Ponyo", the putt putt boat is a simple powered, miniture model.
Here's a website that explains how the boat runs and works. sciencetoymaker
And here's a website that explores the differences between multiple fuel sources. consumerreports
Tomorrow we'll be starting the project that involves making a boat and racing it against each other.
Emmeline, I found the links you posted very educational! I liked how on the first one, it fully explains the process of the engine, explaining the steam and puffs of air. In addition, your second link was interesting comparing and contrasting diesel, biodiesel, and vegetable oil.
