Folding Space
Folding paper doesn't sound very scientific, but there's a lot of physics going on behind the scene. Try folding a piece of paper. How many times can you fold it? Probably seven or eight, but after that, it becomes pretty impossible. Well, did you know that if you were able to fold it 42 times, it would be thick enough to reach the moon? Now that's really out of this world!
Killer Coconuts
When you're staying on a tropical island, you might be afraid of the sharks living in the waters. However, the real danger is on the land and in the trees. Coconuts might be delicious, but they kill more people than sharks do every single year. Cows also kill more people than sharks do. You have a better chance of swimming than standing under a palm tree!
