Now you can learn about hydraulics, whilst launching things at the same time with this DIY kit. It's the perfect mix!

Easy to make in about and hour or two, you can learn about levers, gears and simple mechanics as you assemble a hydraulic catapult and some super cool gear linkages! With the push of a syringe, you can set a range of gears into linear and rotational motion!

Inspired by drawings by Leonardo da Vinci, this DIY kit is safe enough to launch popcorn into your mouth, but powerful enough to knock down small block walls. Complete with great instructions and educational material! Made of sturdy, die-cut plywood, you can even paint it too!

Your kit includes: 41 die cut plywood pieces and a MDF base, 26 wooden dowels and spacers, 1 tube of glue, 1 piece of sandpaper, 2 syringes and tubing, 1 pack of soft clay, 1 elastic, 1 plastic cup and 36 rubber o-rings.

A unique intergenerational kit for parents, grandparents and children to explore science together. It was awarded "2016 Toy of the Year" for building kits by Creative Child Magazine!

What people are saying:

"The parts are well-machined and fit together nicely. I found the best ammo to be aluminium foil balls!"
"My 10 year old grandson loved this, I bought ping pong balls to shoot and they work great!"
"A well-designed delightful toy, my 11 year old son was able to put it together himself, it looks cool as a bedroom decoration when not in use."

Recommended for ages 8 and up.
