My son ryker loved it ,he enjoyed building his own cannon ball launcher .He couldn't wait to show it off to our family. We send the video to my family and they were very impressed in what he had accomplished. It also built his confidence to make more projects in the future. Thanks, kiwico for creating this wonderful site for kids to learn and to be able to enjoy the fun of science and technology .

This was by far a favourite Kiwico kit for my 5 year old daughter. She was very engaged in the building process and played with her cannon for hours on end! It was sturdy and very appealing to play with once built. Worth the money to buy from store.

Fun! Great directions, but the parts fall apart more easily than I would have liked for how much hard play it gets as a cannonball launcher.
