…You can hack your brain to hallucinate?


Want to hallucinate without the harsh after effects of mind-altering substances using just a radio and some ping-pong balls?

The Boston Globe has put together a few easy illusions, hallucinations and psychedelic experiences that can take you on a trip with objects you probably already have around the house and just a few minutes of your time.

The tricks include the Ganzfeld Procedure, the Pinocchio Illusion, the Rubber Hand Illusion, and Purkinje Lights, and each sounds more trippy than the last.

Plus, unlike LSD, magic mushrooms or mescaline, these phenomena can all be turned off just as easily as they’re turned on, allowing you a safe and temporary escape from the trappings of your mind.

…Danger makes the world go slower?

SkydivingEver wonder why time seems to slow down during moments of danger?

According to David Eagleman, a scientist at Baylor College of Medicine in Houston:

    When a person is scared, a brain area called the amygdala becomes more active, laying down an extra set of memories that go along with those normally taken care of by other parts of the brain.

    “In this way, frightening events are associated with richer and denser memories,” Eagleman explained. “And the more memory you have of an event, the longer you believe it took.”

    Eagleman added this illusion “is related to the phenomenon that time seems to speed up as you grow older. When you’re a child, you lay down rich memories for all your experiences; when you’re older, you’ve seen it all before and lay down fewer memories. Therefore, when a child looks back at the end of a summer, it seems to have lasted forever; adults think it zoomed by.”

How did he test this theory?

    Researchers dropped volunteers from great heights. Scientists had volunteers dive backward with no ropes attached, into a special net that helped break their fall. They reached 70 mph during the roughly three-second, 150-foot drop.

    “It’s the scariest thing I have ever done,” said David. “I knew it was perfectly safe, and I also knew that it would be the perfect way to make people feel as though an event took much longer than it actually did.”

    Indeed, volunteers estimated their own fall lasted about a third longer than dives they saw other volunteers take.

Now you know.

…Hidden circles trick your eyes?

Here’s a fun way to fool your eyes: In the picture below, how many circles do you see?

Circle Illusion

The correct answer is 16.

If you still can see them, stare at the “X” in the middle of the image until your eyes begin to lose focus, and the circles should appear.

…Sound can play tricks on your mind?


I’ve posted plenty of visual illusions, but never an audio one.

To take part, just listen to the following video. Then, when it’s done, replay the video to hear the sound continue to ‘creep-up’.
