For the last three days Sue's brother has been up visiting with his Grandchildren. I set up a Marshmallow Catapult Challenge that quickly developed into a major arms race. Here are just some of the models we built.....
Details of how to build your own can be found on the Internet - here is one link.
This final model was so powerful that we were squelching mini marshmallow on the Artex ceiling!
Sue banned us from using it.
I hope you enjoyed it Joe, Summer and Raffi.
