Sugar glass is a drinking glass made out of melted sugar, which will be consumed by the visitors and is intended for one-time events i.e. cocktail parties etc. Once the alcohol/drink is consumed, the object devolves into a lollipop.

By the way, if you’re as obsessed with those gumball stirrers as I am, you can get the tutorial here!
