Pro'sKit ORBI Salt Water Astronaut Educational STEM Kit GE-736

The Pro'sKit ORBI Salt Water Astronaut Kit is a hands-on educational STEM kit that walks and wobbles without requiring any batteries. Powered entirely by a saltwater chemical reaction, it demonstrates alternative energy and mechanical principles in action. It is perfectly suited to young learners aged 8 and up, STEM classrooms, and beginner makers.

Battery-free saltwater power

The kit operates without conventional batteries, generating its own electrical energy using a simple saltwater redox reaction. Just a single drop of saltwater powers the astronaut's movement for up to 30 minutes.

Built-in fuel tank storage

Equipped with a built-in kinetic storage saltwater fuel tank, the model can be operated up to 14 times per mix. This allows for repeated experiments and demonstrations without frequent refilling.

Hands-on mechanical learning

Designed for an estimated assembly time of 1.5 hours, the kit teaches core scientific principles including gear mechanisms and redox chemistry through practical building.
