I came across this video while looking for things of interest online.
It does seem rather random, doesn't it?
If you have ever tackled the subject of thermodynamics in your chemistry classes, this might jostle your memory. The most relevant Wiki article I could think of is the one about heat transfer coefficient.
In short, it's about how heat moves between materials.
Being a bit bored, I tried this out myself using a five-ounce silver buckshot.
Lo and behold, the bullet started to sink into the ice in less than 30 seconds. It was cold to the touch afterward.
I don't recommend doing this with your silver pieces as you might tarnish them by exposing them to the elements. Fortunately, my stash is kept in containers with silica gel packets that siphon moisture away in a remote part of the house. Honestly, silver is silver to me. I don't care as long as it's not radiating something harmful.
Other than that, I think it might be a cool trick to show kids when an opportunity presents itself. I have no idea what they teach in school these days, so maybe it will never happen.
Now, don't go laying 10-ounce silver bricks out on your driveway in the winter.
