Experience 'TENSEGRITY' (tensional integrity) with this easy build and play Tengy Tower! To create a joyful experience for children, we made a series of thoughtful designs for the strings: adjustable length and easy to lock up. Besides, we provided different challenges, from beginners to masters level, for different ages of children. By finding balancing points and anchors in the Tower, they can find out the mystery of mechanics. The discovery provides them a path to becoming future engineers and architects.
