Kids can create more than 100 motorized land and water vehicles out of 108 interlocking parts in the Capsela Max-Out Set. The kit includes easy to understand instructions with illustrations, and discusses 18 physical concepts, including electricity, energy, gearing, buoyancy, inclined planes, and traction. No tools are needed to assemble the vehicles. The vehicles require two AA batteries. This toy merges a kid’s love of vehicles and building into one toy — it looks like it would be fun and educational for kids and parents alike. The toy retails for $100.
