DSDN 112 - Is this going to work?

This effect would be good for my drink because it is unusual and unique. This would look good with the red icing that comes from the top of the glass. I was wondering if there was a glass that had two layers so one layer of the glass could be dry ice and the other would be the liquid I create. Doing it this way would make the drink not infected with any harms from the dry ice itself. I'm going to do a little more research on dry ice and where to buy it from and different ways to use it but this is just an idea for now.
