Peanut Butter Glows in the Dark

The beauty of the natural world doesn’t fade when the sun goes down. Far from it: Glowing organisms and objects create light shows in our forests, seas, and skies. Now you can add your kitchen to that list. All you need is an unopened jar of peanut butter and a laser pointer.

As the mysterious host of YouTube science show NurdRage will demonstrate, peanut butter briefly glows green after exposure to a violet laser. Any peanut butter should work, as long as it’s fresh. The phenomenon is called delayed fluorescence, or afterglow, and is caused by light-absorbing natural compounds called phenols. The same effect can be spotted in other nuts like cashews and almonds, but, as Sarah Keartes explains in The Nerdist, the process of crushing and heating peanuts to make peanut butter really gives the phenols a chance to shine.

This isn’t peanut butter’s first experimental rodeo. Scientists have turned peanut butter into diamonds, and astronauts have explored the fine art of making a peanut butter sandwich in microgravity. America’s favorite nut butter and science go together like … something and something else.

When the hit Star Wars series The Mandalorian premiered on Disney+ last fall, executives withheld merchandise to make sure viewers were surprised by the sudden appearance of The Child, a cooing puppet that appears to be of the same species as Jedi master Yoda. Knowing demand for toys and other items for "Baby Yoda" would be high, Disney stood firm.

Those days are over. Now, fans of the series can buy everything from The Child plush dolls to the space macarons the goblin-faced tyke munches on in the fourth episode of the show’s second season. The blue macarons, dubbed Nevarro Nummies after the name of the planet Mando and The Child landed on in the episode, are available at Williams Sonoma for $49.99.

According to the company’s site, the “ethereal French-style almond macarons” are perfect for “capturing the essence of this scene.” Bear in mind the “essence” of the scene involves The Child throwing a Force tantrum by using his skills to swipe the cookies from a student’s desk while briefly placed at a school.

The precocious creature’s voracious appetite has been a running theme on the series, with some viewers taken aback by a scene in an earlier episode in which he devoured the eggs of a critically endangered frog species. (“Baby Yoda Canceled Amid Accusations of Genocide,” read the Vanity Fair headline.) What will Baby Yoda eat next, and can you buy it? Tune in this week to find out.
