THE BACK YARD A man jumps onto a trampoline with 1,000 set mousetraps on top, and its obviously awesome.

To catch you up, this video is presented by the Slo Mo Guystwo British blokes (named Gavin and Dan) who are self-proclaimed backyard scientists that do interesting or ridiculous science projects and film them in slow motion.

During the life of their YouTube channel, theyve done some amazing things that none of us should ever try at home. (Also this article is not posted to encourage anyone to do their stunts at home.) Lets just say theres a lot of paint splatters and explosions as well as a fair amount of bullets going through fruit and other items. Think lower-budget Myth Busters.

Theres so many incredible moments that you cant see with your own eyes, so we like to show you, they say of their videos in a trailer for their YouTube channel.

I, for one, am certainly glad they do. Watching chemical reactions, chain reactions, and destruction of inanimate objects in slow motion is almost always fascinating. Its sort of like looking at physics through a microscope because you can see so much more than you can normally see.

This time, these two well-prepared fools set up 1,000 armed mouse traps on a trampoline, and then Dan jumps right into the center of the whole thing. Yes, the traps go off spectacularly; yes, it makes an awesome sound; and no, Dan is not particularly hurt during the stunt. The whole thing speaks to my inner child curiosity in ways I wasnt sure were possible anymore.

If none of that convinces you to watch the video, maybe a little advice from Ferris Bueller will help: Life moves pretty fast. If you dont stop and look around once in awhile, you could miss it.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
