What If You Could Shrink to the Size of an Atom?



What if you could shrink yourself down to the size of 1 mm (0.04 in), about the size of a frog’s egg? Actually no, there too many creepy crawly predators, so let’s go smaller. What if you shrunk to 10 micrometers (0.0004 in), the size of an animal cell? That’s pretty cool, but I think we can go even smaller. How about 100 nanometers (0.000004 in), the size of a virus? That’s better, but we’re not in the mood to be swallowed by white blood cells. So let’s keep going. What if you shrunk to 1 angström, the size of the atom?

Why you don't need 8 glasses of water a day | Body Stuff with Dr. Jen Gunter

Dr. Jen Gunter is here to shake up everything you thought you knew — from how much water you need to drink to how often you need to poop and everything in between. This TED original series will tell you the truth about what’s *really* going on inside you.

What If You Spent 24 Hours Lost at Sea?

What If You Spent 24 Hours Lost at Sea?

This man is about to dive 20 m (65 ft) off the top of a cruise ship. What will happen to his body when he hits the water? Well, luckily for him, and others, the impact of hitting the water wouldn’t be the worst part of going overboard. The worst part would be what could come next: being lost at sea. Even if you’re wearing a life jacket, surviving all alone in a giant body of water until someone rescues you will not be easy. What would be the biggest threat to your survival? How could fish eyes save your life? And how long would you have before the water starts breaking down your skin?
