So as you can see from my previous post, I recently discovered “pop pop” boats on a day trip to Whitby. I was interested to find out all about how these boats work and after looking on YouTube I found some great videos by “sciencetoymaker” which show how to make a Pop-Pop engine using an empty drinks can and some straws. I needed some Epoxy glue (which is a very strong and hard setting adhesive) and a hot glue gun. “Sciencetoymaker” also provides templates for making a boat to house the engine, from a milk or juice carton.

I didn’t expect too much success from my first attempt so was amazed when the engine worked the first time I tried to run it! I glued the engine into the boat and tested it in the bath!  As you can see, it works quite well!  I may put a deck and a cabin on the boat, and if I can be bothered I may paint it!
