    Building this working arm (and your engineering skills) is challenging and exceptionally rewarding, especially for the fun that follows: discovering the sequences in which to move its six water-powered levers to make the arm turn, lift, lower, and move blocks (and other components) to create structures. To pick up items with surfaces larger than the scope of its grippers (1.89"), simply remove them to reveal a super suction cup that will lift large items such as your phone (up to 50g), and flat, hard-to-grip items such as a card. Measures 12¾"L x 9½"W x 16¼"H assembled.

    • Build a working hydraulic arm with this fun kit for young scientists
    • Discover the sequences in which to move its six water-powered levers
    • Make the arm turn, lift, lower, and move blocks to build structures
    • Remove its grippers to reveal a super suction cup with which to pick up large, flat items such as a cellphone.

    For ages 10 and up.
