This is a real thing, but I prefer the levitation theory.

How Stores Make Produce Look Better



Grocery stores sell fruit in mesh bags because it's to their advantage for you to buy twelve oranges when you only need two. If the last few oranges go bad before you finish the bag, then you'll go buy more. You might even find a couple have gone bad as soon as you open the bag, because you can't inspect each orange in a five-pound bag before you buy them. They looked so good when you picked them up, and some of that is an optical illusion. The video is only six minutes long; the rest is a sponsor message. (via Geeks Are Sexy

Brainstorm or Green Needle?



The question in the title sounds like we are going to name a new superhero. No, this is another audio illusion that might freak you out a bit. A toy says "brainstorm." Or maybe it says "green needle." You need to decide which one it is before you play the video. Then play it again, thinking about the other option. Keep your finger on the replay button (bottom left on the video), and you'll find that this toy says what you expect it to say, even if you change your mind between plays. Some people hear "green storm" or "brain needle," but that's because they chose to hear it. For some science behind the phenomena, and the actual answer to what this toy is saying, go to HuffPo.

Dazzle Camouflage



We think of camouflage as what animals use to blend in with their background. A ship that has zebra stripes that aren't even straight is not what a normal person would call camouflage.  But a still photo doesn't do it justice, because ships are always in motion, and the enemies looking for our ships are seeing it in motion. If a ship sits still, it's probably not in a battle zone. 

Razzle Dazzle camouflage was developed in World War I in response to submarines attacking them with torpedoes. In order to understand the mechanism behind the idea, we have to put ourselves in the place of an enemy submarine aiming a torpedo. The bedazzled ship doesn't have to be invisible; it just has to be hard to destroy. Did it work? Not as well as hoped for, but any edge is worth the effort to save a battleship and its huge crew. Half as Interesting takes us through the steps behind the design. The camouflage ends around 5:35; the rest is an ad for a good cause.

Bigfoot is Bears

is it time to bust out my "bigfoot is bears" photo collection again? if your mental image of a bear is a thick-furred, fat glossy male bear in autumn, you're probably not prepared for how weird their proportions can look in spring, or when walking upright, like they frequently do.

The Airwalk



The duo known as Shuffle Pack demonstrate the dance called the airwalk. It's darned cool when they get to it, as they appear to float in the air slightly above ground level. Ignore the reference to a "stranger;" they do that all the time. Shuffle Pack consists of 14-year-old British twin brothers Alex and Alister, so they are always in tune with each other. 

The dance itself is an illusion. What's happening here is a classic example of misdirection, like a magician would use. Your eye is drawn to the part of the dance step that does not touch the ground, while the dancer's weight is supported by the other foot at that time. Their tutorials make it look easy, but like the moon walk, the final appearance depends on how smoothly you pull it off. They say that this will really strain your leg muscles if you do it for more than a few seconds at a time.

Amazing Illusion

If you stare at this circle for ten seconds, your brain will begin to perceive that it is a red dot. Go ahead, try it! Crinchy posted this at reddit, and SEILogistics gave a simple explanation.

It's caused by a prefrontal imbalance of the auxiliary nerve on the eye retina created by the spheroid object being stared it. It confuses the obsidian prenatal synapses in the brain.

If you'll notice on your peripheral vision you can see the prenatal synapse snapping on the right of your field of view before it turns red.

As your prefrontal cortex adjust you can see the neuropathic synapse being repaired in your eye and the circle centre returns to its normal colour.

Well, that makes perfect sense.
