“Awesome! The Oakland Ballistics trebuchet was the highlight of our Catapults camp. Kids loved building them and parents were impressed by the knowledge their kids gained. I highly recommend these projects - the directions are clear and easy to follow, the materials are durable and work well, and it’s a great value for the price. We’ll be using these projects again and again in our science summer camps. Thanks!”
