Instead, you can activate and power up the Arachnoid’s fuel battery with only salt water!

As a DIY STEM toy, take your time to follow the included instructions and build this simple eight-legged Arachnoid robot. The metal magnesium plate inside the Arachnoid’s battery can successively provide the Arachnoid with enough power to move around for 4-6 hours.
