Gravity anchors keep floating offshore wind platforms in place by using their own weight. Sold in sets of three, these heavy anchors rest on the seabed and hold structures steady without needing to be dug or drilled in. Children can combine them with floating models such as the spar buoy, semi-sub, TetraSpar or TLP to see how stability comes simply from mass and balance. Through hands-on play, kids discover how engineers use gravity anchors in locations where the seabed allows for this straightforward and reliable solution.
