Mini Excavator

Build your own hydraulic excavator. The same prinicples used in real excavators to dig and move heavy soil are at work in this mini version. This kit uses a first and third class lever to make the arms and shovels move. It uses water instead of hydraulic fluid. Comes complete with all pieces pre cut and ready to assemble (glue included). Excavator stands 30 cm when completed. It is also a good introduction for beginner model makers. Age 8+
