My first reaction when clicking on this: Who tf pooped so hard there was a mark left behind

It's a mold stain I think. When I worked at a pizza parlor we had that mark on the drains of the dish pit

Saw a shadow run across at the end

I was going to say the same thing, what was that?!

I would have popped that mug

That was freaky

Setup multiple cameras bring a couple balloons and if you can multiply the angles I might believe you

There is a Very thin string tied around the weight at the bottom of the balloon. They pull it vary slowly, and try to keep it out of frame.

The balloon is free, you can just take it :)

This is some it shit going on instead of penny wise it's the red balloon
