Here’s an interesting video from National Geographic showing the science behind barefoot waterskiing – and, by extension, waterskiing with skis on.
Staying on the surface of the water comes down to velocity and surface area in contact with the water. A person must be traveling about 34 miles per hour in order to keep from sinking.
This is a good one for kids, too.
