THE KITCHEN Making a peanut butter and jelly sandwich is one of the simplest things you can do, right? You've been making them since you were a kid it might have even been the first "cooking" you did all on your own.

But what if you met someone who had never eaten a PB&J before? What if you had to explain the grade school staple to someone who had never even eaten a sandwich? Making lunch might actually be more complicated than you realized.

That's the lesson these kids learned when their YouTuber dad, Josh Darnit, challenged them to give him exact instructions for making a PB&J. At first the kids seem confident, sure they can instruct their helpless dad on a bit of sandwich making. But when they realize Dad is following each instruction to a T, they start getting frustrated and hilarity ensues.

After several attempts, little Evan has clearly had enough of his dad's antics. "I quit! You're not making any sense!" he yells. "Sorry you ruined it on purpose!"

I get it, Evan. It's frustrating when someone doesn't understand what you're trying to tell them. Fortunately, the family had fun making the video together and probably learned how to work together better than ever before.
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.
