Fun fact - The moon

Don’t panic just yet, but the moon is moving away from the Earth! The moon’s orbit is getting larger, at a rate of about 3,8 centimetres per year. The reason is that the moon raises tides on Earth. Because the side of the Earth that faces the moon is closer, it feels a stronger pull of gravity than the centre of the Earth.

Fun fact - Navel lint

Got something in your belly button? Navel lint consists primarily of stray fibres from one’s clothing, mixed with some dead skin cells and strands of body hair. The rotting cells can create unpleasant odours … so keep that belly button clean!

Fun fact - Vuvuzela

Vuvuzelas only play one note, and it’s B-flat – which is the same note that’s hummed by many of your household appliances, including your fridge and washing machine.
