Construct a ClockThis brightly coloured clock can be constructed in just 10minutes! A great tool to not only teach your kids how gears and cogs work but it will alsohelp them learn to tell time.The clock is spring-driven so no batteries are required, Once you’vefinished construction just wind it up and watch the cogs turn and tick away! Itwill run for over 8 hours with one winding – then your little one can reset thetime and wind the clock and away it goes again.
