Why does pepper make us sneeze? ALSO, is it bad if someone snorts pepper, cause my friend did that for a dare during physics class today.

Sneezing is an involuntary reflex to try and get irritants out of our nose and pepper contains a chemical, piperine, that irritates the mucus membrane of the nose by activating your pain and acidity receptors. So, once it’s in there, your body will totally freak and try to get it out of there…with sneezes…lots of sneezes. As for how safe it is…it’s never good to intentionally irritate your mucus membranes, but as long as it doesn’t become a habit (and I can’t see why it should) your friend should be fine.

What causes a computer monitor to stop working when it is exposed to a magnet???
Well, first off, today’s LCD computer screens won’t get messed up by magnets (unless they’re EXTREMELY STRONG). But CRT (cathode ray tube) monitors can get messed up by magnets. Those more boxy screens work by firing electrons extremely precisely at millions of tiny phosphorescent dots. Hit the green one…green light…the red one…red light…hit the blue one…blue light. Pretty remarkable that we figured out how to turn that system into 50 years of color TV. 
So, as you probably have guessed by now…electrons (being negatively charged) are affected by magnets. If you plop a magnet onto a CRT screen, it will either attract or repel the electrons, distorting the image. It’s pretty cool to watch. Less cool, though, is that the film behind the class can actually get permanently magnetized by a magnet, resulting in the screen becoming permanently distorted. So don’t do that unless  you don’t care about your monitor anymore. 
Today’s LCD screens don’t have any flying beams of electrons for magnets to distort…but they’re still very cool.

Latest Animal Wonders is up!

It’s pretty amazing how life takes us on incredible journeys. I’m so glad my adventure has takes this particular course. I mean, there was a good chance I might have gone to college in North Dakota to run really fast and then what… oh god, I don’t even want to think about it. I hate running.

Let Jessi tell you the story of the founding & growth of Animal Wonders & subscribe to them on youtube!
