Hands-on STEM fun you can build and play

Meet the Smartivity DIY 2in1 Hydraulic Launcher, a compact mechanical kit that powers paper planes and darts into the air using a real hydraulic system. Each project invites kids to assemble the model from safe, high-quality components and then test the results in their own living room, classroom, or outdoor space.

What makes it engaging

  • Action-packed construction and launch experience keeps curiosity alive
  • Step-by-step manual guides hands-on building from start to finish
  • Compatible for ages 6 through 14, with scalable challenges to grow skills
  • Engineered wood components offer a solid, tactile feel and durability
  • Eco-conscious design paired with safe materials for peace of mind

Learning that happens when kids play

As children assemble the launcher, they observe cause-and-effect, test ideas, and refine their approach — all without screens. The dual-function design makes room for experimentation: shape a paper plane one moment, then aim a miniature dart with controlled force.
