Wood and hydraulics combine into a robotic kit that can be built in an hour—an exciting hands-on exploration of hydraulics. Everything you need to build includes Precut wood pieces, plastic hydraulics, and easy-to-follow instructions. Hands-on learning at its best. Building models decreases stress and increases focus, organization, and spatial and fine motor skills. All of our Curious Engineer kits are great Christmas and Hanukkah gifts. Bring all ages together for a fun engineering project. 10x7.5x2" box" Ages 8+ with adult interaction.
