This kids' construction set is an ingenious way to encourage your child's cognitive development as they learn how gears work.

Build a clock within 10 minutes, wind it up and watch it run for over 8 hours. It's wonderful for introducing mechanics and working on those time telling skills.

This easy to build clock whips up in a flash and will fascinate young minds with its turning cogs and swinging pendulum. The clock is spring-driven, so requires no batteries, and is a fun and safe way to teach children basic mechanical principles.
