Scientific Toys

I love Scientific toys. I just returned from Japan with two. A "pop pop" boat and a Stirling Engine. The Stirling Engine is a little more complex and requires some skills. Japanese are very good at their craft. Although the instructions were in Japanese, they are very well illustrated with drawings. I must say the instructions are very clear and I managed to get the engine working. The "pop pop" boat is very simple and easy to assemble. I am very glad to have two working models. Will show you pictures next time.
