This construction kit challenges you to build a fully functional VEX Robotic Catapult! Explore the technology behind some of the most influential inventions of our culture's Age of Innovation! Inspired by ancient Greek and Roman designs, this modern Catapult has a ratcheting winch that can control the distance projectiles are thrown. Crank the winch to its maximum tension, and you can hurl balls over 3 m (10 feet)! Teaches important STEM principles through hands on learning. Features two alternate builds for more robotic fun! Two balls included. Batteries not required. 8+ years.
The VEX Catapult Toy helps you to introduce children to the world of STEM (Science, Technology, Engineering and Mathematics) through play. It has 100 pieces that are simple to put together and which stay in place for long-lasting models. This product comes with plans for three different sets, a race car, a trike and a catapult. The two balls provide ammunition for shots. Simply place one in the basket, crank the winch and fire. It has wheels that make it easy to roll around. You can use the parts to create models from your own imagination for even more creativity and fun. Use this toy to teach physics principles, as well as a history lesson as you describe how this Greek invention helped to modernize society. 

If you’ve changed your mind about keeping your purchase, please return it in its original condition with proof of purchase and we’ll exchange or refund it. Unless faulty, this should be within 35 days of receiving your order. By original condition, we’d expect this to mean that you’ve kept packaging and labels, and that the item is undamaged and unused.
The catapult will capture the attention of many kids and when they see how it launches balls, they’ll cling to it. However, on the exact same note, it might be a little hard to set up in order to get the ball to launch. Children will need some patience in order to get it to work, but it is well worth it since as soon as it works, the youngsters are going to be impressed with how it carries out.
What I did notice, however, was that the ball had way too much power directed in the wrong direction - so I do believe that with correct geometry, a backward launcher could also be done with just 1 piston like John's. I know it's not clear what I mean by having a forward launcher geometry flinging backwards instead, but it's late, so I'll let Aaron or Ruiqi explain for me if anybody has questions.
This modern Catapult has a ratcheting winch that can control the distance projectiles are thrown. Crank the winch to its maximum tension and you can hurl balls over 10 feet! This cool construction set teaches kids important lessons about variable shot power and how machines store kinetic energy. Includes more than 100 easy-snap pieces, 2 balls, and instructions for 2 alternative builds.
