When Super Glue first came out I was doing some electronic work at Oceana Naval Air Station ,in the RATCC ( Radar and air traffic control center).We often started our work at 3AM to avoid problems with the momentary glitches we caused in the communications while transferring equipment.By the time most of the folks came in, we were on our lunch break...and up to no good. We had some two part CA from Kodak to use to apply some metal to glass. It was amazingly powerful.
Outside the door of our work room, we glued a quarter to the linoleum floor. For an hour people tried to pick it up (From seamen to Captains). They all gave up after several tries. Finally a person buffing the floors came along and decided to use his gum scraper. He pried on it and popped off the coin....with a nice piece of floor still attached. He was really pissed, and when he saw us watching ( and laughing), he said he was going to get the maintenance supervisor about how we had damaged the floor. He left the coin and piece of floor next to the hole. As soon as he left, I took the piece, used a soldering iron to detach the coin, bonded the piece of linoleum back into place with the CA,quickly sanded it smooth, and used the buffer to buff the spot.The repair was invisible. We left another quarter sitting on the floor as if nothing had been moved. When he came back with his supervisor, he looked down at the coin, thinking we had just placed the piece of tile back in its hole. He told the supervisor that the coin was fused to the floor with some sort of strong glue, and couldn't be removed without the whole piece of tile being ruined, and how we must have placed the piece back in the hole. The supervisor reached down to check, and picked the coin right up. The floor was undamaged, and shiny.
He looked at the guy, grinned at us, and walked away with the coin. I don't ever remember getting a more f^c# y@u look than that guy gave us. We jokingly considered gluing his mop bucket to the floor one day, but decided against it.
