Update: Don't try this at home or anywhere. This creates one of the worst things I've ever personally made.
It started off fine as I mixed them. It changed to the color of the toothpaste (white), and vaguely resembled lotion in appearance. Then I made a horrible error. I touched it.
I touched it and immediately nearly all of it adhered to my skin. Everything I touched thereafter gained a thin layer of vaguely minty-smelling slime. It was some unholy abomination of a substance. Water couldn't get it off. Soap couldn't get it off. It stuck to tile, it stuck to wood, it stuck to carpet, and it doesn't adhere to itself, so no amount of scraping with my hands could get it off, it just spread more.
Finally I had to get a sacrificial towel to wipe the substance off of me and everything I'd touched on the way to get the towel. Despite washing and scraping with a brush, my hands still smell like mint and feel slightly slimy. I can feel my skin burning from the mint flavoring of the toothpaste nearly an hour after getting it off my skin. I didn't even know that was possible until today. I could have gone my whole life without knowing that, but now I know.
I have no idea what the ad actually wants you to do with this concoction as I did not click through, but I can only assume it wants you to use it to torture prisoners or something, there seems to be no other possible purpose for it.
