Since General Science students are studying surface tension, I thought you would all appreciate this video. It is NOT how Jesus walked on water!
But how do you measure surface tension to predict the speed at which you would have to run to stay on the surface? We could probably figure out a way. Here is an instrument that gives one method of quantifying surface tension.
And speaking of surface tension in colder climates brings up the use of snowmobiles in summer or waterskiing behind horses in a river!
