News: Artist Uses 300 Apples to Power 30 LEDs for 1 Electrified Fruit Battery Science Experiment

You've probably seen the classic fruit battery science experiment a thousand times, but I doubt you've ever seen it turned into an art project! Photographer Caleb Charland uses everyday objects like apples, coins and vinegar to create makeshift batteries, then takes these gorgeous long exposure photos. For the apple tree photo, Charland got about 5 volts for every 10 apples, so he had to wire 300 apples to power the lamp for several hours. He used a zinc-coated galvanized nail and copper wire...

News: This Levitating Light Bulb Defies Gravity (And Ditches Unsightly Power Cords)

Helping to prove that science is way awesome, an 18-year old electrical engineering student has successfully made a light bulb float. His name is Chris Rieger, and he's been working on his "LevLight" project for about six months now, with pretty amazing results. This feat of ingenuity was accomplished by using magnetic levitation, although that over-simplification masks how considerably difficult this undertaking was.

News: Rocket Power Your Lazy Boy

Since the days of Archytas, rocket propulsion has been the Holy Grail of aeronautics. Thanks to Galileo's inertia, Newton's laws of motion, and the "father of modern rocketry," Goddard, space is not a complete mystery anymore. Rocket-powered aircrafts have evolved from the first liquid fuel rocket in 1926, to the Soviet R-7 which launched Sputnik, to NASA's Saturn V that propelled Apollo 11 to the moon. Today, even billionaire tourists can enjoy space, like Microsoft's Charles Simonyi and Cir...

Food Tool Friday: This Cloth Bag Is Actually a Powerless Slow Cooker

Meet the Wonderbag. The "first non-electric slow cooker" uses an insulated bag made of poly-cotton fabric, polyester, and repurposed foam chips. You bring your one-pot meal to the desired cooking temperature, usually via the stovetop. Then you turn off the heat, pop the pot into the Wonderbag, and it will continue to cook thanks to the retained heat in the bag.

News: Transmitting Power... Tesla Style

Matthew Inman, who runs the popular web comic The Oatmeal, decided to test his new hand-held "Tesla Cannon" (which is essentially a small-scale Tesla coil) on one of his friends. His friend, Matt Harding, held a giant light bulb and allowed himself to be shot with the Tesla Cannon.

How To: View the Battery Percentage on Your iPhone SE to See Exactly How Much Power Is Left

There are two main ways to view how much battery is remaining on an iPhone: the battery level icon and battery percentage. Out of the box, the second-generation iPhone SE only shows the battery level icon in its status bar, which only gives you a rough idea of how much juice is left. But there are ways to view the exact percentage instead.
