Build Your Own Hydrapult - a fluid powered catapult
By moving the way the swing arm is pushed by the syringe, the finished hydrapult gives 3 different trajectories – perfect for inquiring minds that enjoy testing ideas (and even learning about graphing)! Lots of educational material about levers and simple machines, and plans to make a target. Test different materials and learn about density and air resistance.
Great for makers and tinkerers, and perfect for programs related to robotics, levers and simple machines, fluid dynamics, engineering and invention. But don’t forget to just have fun!
Pathfinders designs and manufactures wooden science kits for educational and recreational use. They're based on Vancouver Island, British Columbia, Canada. They spend time with kids in schools, making and using the kits to see how well they deliver curriculum for teachers, and to make sure they're engaging and appropriate for both fun play and educational aspects. And they definitely are! Pathfinders aims to provide such fun and interesting kits that they will be an attractive and desirable toy for anyone from a small child, to an executive planning a friendly take over.
Pathfinders are an environmentally friendly company and use recyclable materials, natural, untreated wood, and local resources and production as much as possible. All of their kits are tested to make sure they are 100% safe, so if the dog (or a child) eats the glue then s/he will not be exposed to any unsafe levels of chemicals of any kind. Pathfinders are members of One Percent for the Planet, donating 1% of sales to protect, and enhance the natural environment.
