There Are Only Three Colors In This Optical Illusion

Take a look at the picture above. See the color blue? If you do, know that it's not really there. But there's no need to run to your eye doctor—it's actually your brain that's playing tricks on you.

Akiyoshi Kitaoka, a psychology professor at Ritsumeikan University in Japan, is a pro at creating optical illusions that make viewers second-guess their ability to see things clearly, as elements appear to shift, warp, and transform. One of Kitaoka's illusions (above), which was recently shared by IFL Science, uses different colored segments to form a vibrant swirl pattern that looks pink, orange, blue, and green, but in reality there is no blue in the image at all.

So what are you seeing? According to Kitaoka's website, the light green and light blue spirals have the exact same color values: R=0, G=255, B=150. But our brains process the spirals as different colors depending on the hues that segment them. The light green stripes in the "blue" swirls are sandwiched between pink stripes (which make the green appear blue), while the green stripes in the green swirls are flanked by orange stripes. Kitaoka used the same idea (known as the Munker-White illusion) on a series of hearts.

Never Lose Your Stuff While Working Out With This Handy Storage Water Bottle

Bindle Bottle

Workout clothes are not known for having the roomiest pockets—if they have pockets at all. But when you hit the gym, you don’t want to carry a bag. So why not stick your loose stuff in your water bottle?

The Bindle Bottle is a metal water bottle that comes stacked with an extra storage container that can fit small items like keys, headphones, Chapstick, or your swimming goggles inside.

A product shot shows a black, stainless steel water bottle twisted apart to reveal keys and a phone inside.

The storage canister sits at the bottom of the water bottle. It has a normal screw top cap that you can use to fill and drink from the bottle. (The company also plans to offer options with straws or coffee lids.) When you want to retrieve your hidden stash of stuff below, you just have to twist off the bottom, where it stays nice and dry.

The side of the bottle meant for liquids holds 24 ounces and has a dual-wall design to keep your coffee hot and your water cold, depending on the day. The storage compartment is a little more than 4 inches deep, so it may not fit most smartphones, but it will certainly fit your gym snacks. Priorities.

The Bindle Bottle is currently available for pre-order on Kickstarter from $31.

Meet the 12-Year-Old Boy Who Makes Surreal-Looking Dolls Using Found Materials

Some dolls are cutesy, but not Callum Donovan-Grujicich's fantastical creations. As Bored Panda reports, the 12-year-old artist from Whitby, Ontario crafts tiny, surreal-looking figures, some of which have won art show prizes and been featured in national magazines and on TV.

Donovan-Grujicich first began making art dolls around two years ago, when he was 10. The bodies and faces of the dolls are made from clay, and the limbs from stuffed cloth, but the young artist often uses found objects—like bits of old metal—to create facial features or accessories like hats and jewelry.

"Found objects are a big part of his process and often, he says, the inspiration for the whole sculpture comes from some rusted piece of metal," Donovan-Grujicich's mother, Julia Donovan, tells Mental Floss. "He loves to collect old-looking scrap metal and anything else that he finds interesting."

Aside from art classes at a local gallery, Donovan-Grujicich is entirely self-trained. Someday, he hopes to earn a master of fine arts degree to teach and make art, but for now, the preteen continues to hone his unique aesthetic by making dolls and creating stop-motion animation and live-action films with his brother.

Some people might view Donovan-Grujicich's figures as grim—especially for a kid—but his mother thinks they simply provide a different perspective on beauty.

"A lot has been made of the darkness in Callum's work, which I think has been completely overblown and misunderstood," Donovan says. "Callum is sometimes serious, but not a dark person at all."
