"Water striders don't really stride, they row on the water. But their legs are spindly and don't seem good for paddling. David Hu, mechanical engineer at Georgia Tech, wanted to understand the basic physics of how water striders glide. By filming them stride on food coloring and building his own robotic strider, he found out that the secret to the stride is in the paddle."
It's Friday, so it's time for a new Science Friday video. Science Friday
