12The experiment

To test this, an experiment was conducted in which an owl was made to fly from one side of a large room to another with nothing in it other than a microphone. The sound recorded was not even audible. Unfortunately, there is a sad angle to this advantage. Owl’s feathers can retain water easily which makes it dangerous for them to hunt in wet weathers or even approach a water body to drink from.

15The miracle of liquid oxygen

Liquid oxygen exists between −218.79°C ( −361.82°F) and −182.962°C ( −297.332°F) and is a bit denser than ordinary water. The reason we’re calling this liquid a miracle is because when it is poured into a strong magnetic field it gets suspended. The liquid doesn’t obey Curie’s law and behaves like a paramagnetic material.
