KidzLabs Electric Marble Run. 4m. The KidzLabs Electric Marble Run lets you build your very own motorised marble run, a visual learning tool that teaches the laws of motion! Similar to those spiral wishing wells you drop coins into at the mall, watch as the marble travels around the chute, rather than rolling straight down the hole. Watch it drop lower and lower on the spiral as friction gradually slows it down, making it seem as though it's moving down a long and spiralling ramp!
