Plastic bottle cap (or engineer a replacement with craft sticks for older kids).Craft Sticks ( Jumbo craft sticks work better than regular craft sticks but you can use either size!).To start I will shared a common and simple design using limited supplies, then I will share an even better design we developed. The most popular, durable and easy way to design a Catapult is using the ever popular craft sticks, also known as Popsicle sticks. How To Build a Catapult with Popsicle Sticks It’s no wonder catapults still capture the imaginations of students everywhere. It’s design may be relatively simple, but it packs an incredible punch and is a wonderful way to dig into STEM for all ages. Some catapults could launch projectiles weighing over 350 pounds over 300 feet! This weapon of warfare proved incredibly effective and was a key weapon of warfare until Medieval times. This classic STEM activity was first invented in 400 BCE! Invented by The Greek Dionysius the Elder of Syracuse. And that was building the much loved catapult! So this week we set about fixing that.īuilding catapults is an Engineering challenge, where students learn how to follow a design process, but also learn physics and maths. At least not as a stand alone STEM project. But there was one thing we had never done. Our Craft Stick Launchers were a massive hit both with our kids and with kids around the world. In the past we have built some really fun projects. Or visit our YouTube channel to see if the video has been uploaded there. Not seeing our videos?

Hitch cords that are purchased through the Teufelberger supply network do not bear the required labeling, for compliance with the Rope Wrench PPE Regulation Approved kits. PLEASE NOTE: For compliance labeling reasons, Hitch Cords must be sourced from ISC (via your ISC Retailer). Aluminium HMS Karabiner (Supersafe Triple-lock Gate) Squirrel (Aluminium) Tether, with built-in Squirrel Pulley (Bearing) The PPE Regulations Certification applies to kits when used in their entirety, in accordance with the User Instruction Manual. The Rope Wrench system has been third-party tested and certified by a Notified Body, to PPE ‘Regulation 2016/425′, allowing users to climb in compliance with the latest European best practice regulations. The Rope Wrench allows easy horizontal movement, with greatly reduced friction on re-directs (compared with DdRT). This allows the operation of the hitch, without the need for a double-rope system. The Rope Wrench shares the user’s weight between the Wrench and the hitch. This effectively provides a contained double rope system, on a single rope. The Rope Wrench provides an ‘S’ bend in the rope above the hitch cord. The ISC Singing Tree Rope Wrench has become a well-established, popular tool within the production climbing industry and in tree climbing competitions.
