Bored or High? #2: walking on water

Speaking not at all from personal experience, I can picture the following study being conceived in a smokey lounge in the shoddy digs of some second year physics students. “Like, dude, imagine if there was a bit less gravity on Earth, and we could walk on water, and stuff”… Also this. And so it is that a group of Italian researchers,1 set up a study to figure out how much gravity needs to be relaxed before humans can walk on water, a feat ordinarily “precluded by body size and proportions, lack of appropriate appendages, and limited muscle power.” These researchers had access to some serious kit, because not only did they “use a hydrodynamic model to predict the gravity levels at which humans should be able to run on water”, they also tested the model using a reduced gravity simulator, like so.

The model they used had been expounded to explain how the rather awesome Basilik Lizard runs on water:

The conclusion?

The results showed that a hydrodynamic model of lizards running on water can also be applied to humans, despite the enormous difference in body size and morphology.

Good to know.
