Science lesson at the Rat’s academy…

“The Professor emitted a series of squeaks and six paws shot into the air, each little rat trying to reach the highest. Professor Rodoric tapped a small grey eared rat on the shoulder. He clapped his little paws together and rolled up a sleeve, whiskers trembling with excitement.

The grey eared rat plunged his paw into the liquid then removed it from the mixture shaking droplets back into the bowl. His paw had vanished.”
