That’s just lack of creativity from your part.

The OP didn’t say the composition of the pedestal, if it has cavities, its temperature…

It won’t float away if you freeze it first, of course it will sublimate away but not all at once.

Edit: Melts, doesn’t sublimate, still won’t melt all at once though.

I’ve also heard that electrons in them cannot be relied upon - especially to be anywhere that they say they will (instead, they zip off to the other side of the whole galaxy/universe, then before you can tell anyone they’re gone, they are back again!) :-P.
