A lot of things can kill you but here are some surprising ones that you probably never knew about.

Enjoy!

This is the ultimate video to illustrate that “the dose makes the poison.” ASAP Science explains how much seasoning, how many cherry pits, and how much loud music will murder you.

Was anyone really surprised to learn that only a few cherry pits will kill someone? This video makes marijuana look surprisingly safe by comparison. Here’s something to reassure you if you ever swallow a cherry pit. They’re not kidding when they say you’ll probably be okay if you don’t chew it. Technically, cherry pits don’t contain cyanide, they contain amygdalin. There are enzymes in the gut that can turn amygdalin into cyanide, but the body regularly deals with small amounts of cyanide because quite a few thing contain some amygdalin.

The problem is when you chew cherry pits. The pit itself also contains one of these enzymes—emulsin—and chewing the pit will naturally mix the amygdalin and the emulsin to create cyanide. In that case, consuming a cherry pit can be very dangerous.

The Backwards Brain Bicycle

A good demonstration of how we learn and unlearn tasks like riding a bicycle.

Enjoy!

Destin of Smarter Every Day fame has a challenge for your brain: a bicycle where the handlebars turn the front wheel in the opposite direction of a typical bike. For example, turning the handlebars left turns the wheel right and vice versa. He warns you it’s harder than it looks.

The hack that pulls this off is a simple one compared to bike hacks we’ve previously covered. Gears on the head tube make this possible. It was built by his welder friends who challenged him to ride it. He couldn’t at first; determined to overwrite his brain’s memory of bike riding, he practiced until he finally succeeded. It took him eight months. When it was time to ride an old-fashioned bike, it only took him about twenty minutes to “un-learn” the Backwards Brain Bike. Destin’s biking illustrates neuroplasticity, memory, and learning in a fun way (fun for us; no doubt frustrating for him).

As a testament to the sponge-like brains of youth, Destin’s son learned to ride the Backwards Brain Bike in only two weeks.
