Shark Fin Ice Cube Tray

A cold drink is more entertaining when it looks mildly unsafe. The Mustard Shark Fin Ice Tray makes four shark-fin-shaped ice cubes at a time, designed to float at the surface rather than disappear into the depths. That floating fin is the whole joke, and it’s a good one: your glass gets a tiny lurking predator instead of another anonymous lump of ice.

This suits the friend who enjoys a visual gag with their drink, especially if they’re already partial to sharks. It doesn’t need a themed party to make sense. A fin poking out of an otherwise ordinary drink does enough on its own, without turning the entire kitchen into an aquarium.

The four-fin capacity keeps this firmly in small-batch territory. For a few drinks, that’s manageable; for a roomful of thirsty guests, you’ll need to freeze ahead. We like it as a small, silly gift with one very clear job.
