Norwegian's new ship features Metropolitan Bar, a sustainability-focused venue that serves cocktails made with would-be food waste.

The vodka and the watermelon somehow do not combine. It becomes a novelty drink fail, and you and your friends have a bottle of vodka to contend with, without the friendly addition of cubed fruit.

Namely, while the flesh of the watermelon, that receptive vessel into which this bottle of vodka is supposed to eagerly flow, is rather spongelike, it is a sponge that's already full - of watermelon.

Since watermelon has a spongelike texture — not unlike that firm green foam florists use to keep their arrangements in place — the bottle's contents will be soaked up by the fruit.

Snap off a piece of wire hanger. Attach it to a drill. Introduce the wire hanger inside the watermelon and power on the drill to blend the inside. Pour a bottle of vodka through the hole.
