Has anyone ever tried this?

Yes, that's right kids! Tell your dealer goodbye and worry no more about winding up naked on the roof of an office building after a bad trip. Now you can be stoned out of your mind by building a homemade deprivation chamber out of some regular, completely harmless household objects.

You are going to need three things: a ping-pong ball, a radio with headphones and a red light.

Step 1: Turn the radio to a station with just white noise (static), and put on your headphones.

Step 2: Cut the ping-pong ball in half and tape each half over your eyes.

Step 3: Turn the red light so it's facing your eyes.

Step 4: Sit there for at least a half an hour.

Step 5: Follow Ben Franklin and your new friend, Harold the unicorn, into the gumdrop forest, and live happily ever after.

It's called the Ganzfeld effect, and it works by blocking out most of the signals that go to your brain. It's the same kind of effect you get when looking into a soft light for a while and lose vision, except at a larger scale.

The sound of the white noise and the light from the outside of the ping pong ball are eventually ignored by your brain. With all those signals out of the picture, your brain has to create its own, and this is where the hallucinations come in.

I'm going to try this tonight, for sure.
I have ping pong balls I think, red light on a big monitor in a dark room should be fine for the light source i'm hoping...
 
Just realized I never got around to doing this.
Pingbong balls in hand, red plastic tupperware bowl selotaped to ceiling lampshade, white noise and headphones, camera to record it all.

Be back in an hour!
 
that was a bit weird.

nothing as clear as the duck at all - first 5 minutes was nothing, and then I felt a few minutes of almost desperation as my eyes were darting around trying to foxus on something.

after that, lots of shapes. Nothing clear, just shapes coming out of the orangey light - always purple. they'd form out of nothing, the contrast different quite clear, and then fade away whilst moving.

if i heard a background noise, everything would go back to plain and normal. Another few minutes, and more moving noises.

About 30 mins in, the sound became a lot louder, and I heard "crickets" over the top. Very strange as I could listen just to them, and the shapes were a lot more distinguishable - stars, silouttes of things. Also, the orangey light would fade in and out.
First time this happened, I had to try and smell if my lamp shade thing had caught fire!

Nearing the end of the hour, I felt incredibly relaxed and sleepy. As my eyes began to close a little, shadows of eyelashes could be seen, and then they were moving around, becoming very clear uniform 'spikes', and then fading back into blurry dark areas.


tomorrow i'll do it again but -

a) louder noise. Either better headphones, or also have external speakers around my bed playing the same as the headphones
b) turn off HTPC. I thought I could hear the HD spinning for the first 20 mins
c) try during the day/evening when i'm not at all tired
d) longer than an hour - on one hand, that felt like a week. Then again, felt like 5 minutes.

I really want to find the talking duck. So far, nothing incredibly over the top, but a very strange experience.

Oh, and video is just me lying there. THroughout the whole thing, i didn't want to talk incase it stopped everything!
 
i'd say the pingpong ball is essential - it's comfortable enough, and it completely diffuses the light evenly - you can't see anything, no shadows, just a very uniform light. Also leaves space for you to keep your eyes open rather than toilet paper or anything else.
