Glitch or intentional?[edit source]
If you place this ingot in a room where two sims are woohooing and then take it out of the room once the hearts start appearing, they will stay there forever. I have put it in my sims' personal inventories, as well as the shared family inventory, but the hearts didn't go away. It does not appear to affect the sims' behaviour, though.
Here's what happened: So I have my alien Sim, Elias, and I made her transmute metals as many times as possible. The final result was WooHooium made from Platinum, so I guess that's another way of getting it! —Darkus R. 00:15, October 3, 2016 (UTC)
