Tin Can Edge Detector Robot


First, there’s the learning experience of building it (you provide the empty soda can and small screwdriver). Then comes the fun and suspense of watching it move across a table, get right to the edge, and whoa! How does it know?! Requires 1 AAA battery. For ages 8-12 yrs, from Toysmith.
