Humans have been talking about walking on water for centuries, but the water strider has accomplished this feat for quite some time. Join Biomimicry 3.8's co-founder and visionary, Janine Benyus and discover the amazing talents of gerrida (aka water striders).

The next time you’re at a pond, look on the surface and you’re sure to find a water strider. Those are those spidery-looking insects, maybe with four legs, that literally skim their way across the surface of the water. The water has what’s called surface tension on the top that’s like the skin of a custard or something. The water strider is light enough and its weight is dispersed enough and its feet are shaped in a particular way to just dimple the water. It uses those dimples in the water to row; it’s actually rowing with those dimples.
There’s a group at MIT who made a little mimic of this and created a little device that will row itself across the surface of the water. Life uses all kinds of mediums that we (humans) don’t use. We move through the water but we don’t really use the surface of the water… the surface tension of the water like the water strider does. It’s amazing.
