A
Bananas are radioactive
Bananas contain potassium-40, making them slightly radioactive. Eat enough and airport scanners might even notice.
B
There are more trees on Earth than stars in the Milky Way
Next time you walk through Epping Forest, remember you're surrounded by more trees than our entire galaxy has stars.
C

Stomach acid is strong enough to dissolve metal, so your body quietly replaces the lining every 3-4 days. Handy, that.
D
Octopuses have three hearts and blue blood

E
