An ant appears to be trying to roll a perfectly spherical droplet of water back to its nest. Photographer Rakesh Rocky from Warangal, India, came across the plucky insects with a ball. But although the ball may have looked like a water drop, it was actually a water-absorbing polymer - or water gel - a biodegradable, non-toxic absorbent crystal alternative soil for potting plants. It can absorb approximately 400 times its weight in water.
