If the end of the day can´t come fast enough, and you´re bored, why not try hallucinating?
Optical Illusion makes you trip.
The optical illusion in this video creates a strong, drug-free hallucination using the motion after-effect illusion. All you have to do is follow the instructions in the video and in less than two minutes you can have a short-lived natural hallucination.
For extra trippiness, add weed!
