ice shot glasses?

Sometimes a product seems like a really good idea until you think about its practicality. Case in point: Ice Shot Glasses.

Now I'm sure that those who like to drink probably have seen these before, but since I don't it shouldn't come as a surprise that I'd not heard of them before last week. I wasn't so much thinking of putting alcohol in them as figuring out what else I could do with them. I've only found two decent looking versions: that above and this one. I seriously considered getting a mold for Banik, but then the logic invaded.

Sure they keep things cold, but they also melt. So whether it's a dipping sauce or pickled ginger it's just going to get watered down even though it stays pleasantly chilled. You could make them out of different things, but then what?

Perhaps if you intend to eat the cup all along. Of course, then it has to be something soft enough to eat. Maybe if they were made out of jello and actually escaped the molds intact they could be filled with something. I wonder if you could fill them with homemade ice cream and then fill the inside with what you'd usually put on top? Still doesn't seem useful enough.

Ah well, it seemed like a good idea at the time.
