A cocktail inside a hollow ball of ice that you shatter to drink

Cocktail Chemistry explains the drink's mechanics: you create an iceball using a cheap latex ice-sphere mold, melt a hole in the top with a soldering iron and extract the water from inside with a syringe. Freeze the ball in a tub until you're ready to serve, fill it using a funnel, and garnish with citrus peel -- serve in a rocks glass and smash with a small mallet. (via Neatorama)
