Beakman explains why your house creaks at night and then explains the purpose of snot and mucus in your nose.
Beakman uses the laws of gravity to explain why people don't fall off the round world. Galileo shows the effects of gravity. Next, Sir Isaac Newton explains inertia and how a seat belt helps save lives.
