Thanks to the Internet and science, there are a lot of myths that have been debunked. Oh yeah, and don't forget Mythbusters. So here are some myths that you might still believe.
- Adding salt to water will make it boil faster - I remember learning this in science class in middle school. Salt was the catalyst that caused water to boil faster. But that's not true. In fact, adding salt will make it take longer. The reason to add salt is to add flavor to whatever you're boiling, and it also helps when making pasta because it's better to boil pasta at a higher temp.
- Cracking your knuckles causes arthritis - There has been no link found between cracking your knuckles and arthritis.
- Dropping a penny from a tell building will kill someone - The penny just doesn't have enough mass to do anything. Now follow up the penny with a bowling ball, and yeah, that'll do some damage.
- The sun is yellow and orange - No, it's not. Well, sort of. Yellow and orange are the only wavelengths that get through our atmosphere and reach our eyes. If you were to look at the sun it would be white because it's essentially all the colors at once.
- Your appendix is useless - You would hear this anytime you would hear of someone that had appendicitis. You can remove it because it doesn't do anything. Not true. It's now believed that your appendix is home to "helpful bacteria" that fight off disease. And when you're a kid it help form antibodies and white blood cells.
