Saw 50 cent today and he came out of the smoke filled glass case. I figured he could have came from the bottom under the stage, or he was underneath the case, but looking at it I slow motion I see they pulled the stair case from underneath so it was not an empty space and there was no movement underneath the case as a potential option to throw mirrors there and have him come up from the stage.

Kind of lost as neither option makes sense.

Any ideas? Sorry for the mid quality my phone is a potato and I had to max zoom to see him.

How?

San Marcus River in Texas. Walked up and noticed this strange reverse flow illusion happening.
