Chemistry / Ice reaction to a specific unknown metal/alloy
« on: 05/11/2019 20:01:51 »
Ok, now what I'm about to describe may sound completely absurd but I have witnessed this with my own two eyes and know for a fact it isn't some simple trick, but I would like to know why and what metal/alloys would cause this.
Years ago I knew someone that had these simply metal cups, and when you would put a plain normal ice cube into them the ice would literally melt right in front of you but no water was left into its place, basically the ice sublimated, so it went straight from a solid to a gas state in under 1 minute, and as a result the cup would be ice cold but the ice was gone and your drink would be cooled but not diluted like if ice was left to sit in it.
I get the concept of sublimation, but my question is what metal/alloy would cause such a thing to happen??
I have searched countless places and everything just comes back to dry ice, but the ice cubes that were used were not dry ice they were just normal water, frozen in an ice cube tray, no trickery played a part in what happens.
Can anyone help me figure this out please and thank you??
