Someone posted in Facebook, a picture of a cat in a staircase, and asked people to judge the cat is going up or down.

A person wrote a comment “The people makes this up must do acid”.

What does “do acid” mean?

It's a psychedelic drug that makes you hallucinate.

It's old slang for taking the hallucinogenic drug, LSD.

By the way, the cat is going down the stairs.
You can tell this from the overhanging pieces on the steps (called the nosing of the tread, apparently). If he is going up the stairs, then a person walking down would be forever tripping over them.

It seemed the picture was formed by imposing a cat picture on a staircase picture.

The annotations in the picture are not clear:

The upper annotation: "If the cat's left palm is resting on this tread, then its left leg is too short compared with the right leg".

The lower annotation: "If the cat's left palm is resting on this tread, then we can see its left palm, but we can't".

Maybe you should add a little acid to your diet to become less sure. :crazyeye:

And to further clarify why it's called 'acid', the full name is lysergic acid diethylamide.

The acronym comes from German name Lyserg säure diäthylamid.

Here's an interesting video of an artist drawing successive self-portraits under the influence of LSD. One might suspect the Cubists of taking it if that movement didn't predate LSD by 20 some years.....
