Challenge your expectations of gravity with the TOTEM Intelligent Spinning Top. Tucked inside this minimalist top is a gyroscope. Sensing its own rotation and using its own motor, this unique feature enables the top to spin for hours on end. In fact, TOTEM can spin for more than four hours without any human intervention. Going even a step further, TOTEM is self-balancing. Even if you knock this top mid-spin, it will sense its movement and correct its balance. Measuring just under two inches tall, TOTEM features high-quality ABS plastic. This helps the top be more resistant to impacts, pressure, and friction. Incredibly, it can spin on just about any flat surface. It gets its power from an ultra-compact CR2032 button battery.
Likewise, the gyroscope, motor, and sensor are all impressively small, keeping a slim profile for the top.
