Carbonation

(the Hope Scholars call it "acid," which I think is sort of interesting)

This is a bird's eye view of 7Up in one of our new tumblers. We found them for only R3.99 each. This was really lucky because we've broken so many and had to replace them for the sake of apartment deposit retrieval in a few months. The only one we haven't had to replace is the big honker glass because, being a big honker, it never falls over.
