Holy crap, normal water can behave like bouncing rubber in space


Surface tension in a weightless environment is awesome. I’ve observed the effect of small water droplets bouncing off a water surface sometimes in sinks here on Earth, and wondered why that might happen. This video doesn’t explain it, but I wonder if surface tension naturally aligns the surface molecules with a particular charge facing out, and hence for small droplets at the right angle, the same-charge repulsion is enough to keep the droplets separate.
