Doorway Effect: Psychologists believe that walking through a door and entering another room creates a “mental blockage” in the brain, meaning that walking through open doors resets memory to make room for a new episode to emerge. This is...

Laughter is universal and unifying; it helps break the ice and is notoriously contagious. If you see a person or group of people laughing, the odds are high that you might also join the laughter train. Laughing along helps us cope with...

At high speeds, wheels may appear to be turning backwards, creating an optical illusion known as the Wagon wheel effect. This happens because our brains fill in gaps between images to create the illusion of continuous movement. As a...

TikTok's inversion filter reverses a facial selfie and shows you what your face looks like when its not reflected in a mirror. Or, in other words, how the world sees you and not what the mirror shows. Thus, the effect of this reversal is...

The difference between air-drying and tumble-drying is that air-drying keeps the cellulose fibers from reforming their hydrogen bonds more effectively, which makes the towel feel a bit fluffy. Tumble drying, on the other hand, causes the...

You may have noticed in movies and tv shows that when a bomb falls through the sky, it makes a whistling sound. This has to do with the fighter planes and bomber planes of world war 2. During the second world war, German air force...

Laughing gas or nitrous oxide is a chemical compound used in medical settings, especially in surgery and dentistry, for its anesthetic and pain-reducing effects. In this video, we will discuss what laughing gas is, how it was discovered...
