In an award-winning campaign for Suntory Whisky, creative agency TBWA\Hakuhodo used a CNC (computer numerical control) milling machine to carve the coolest ice cubes we’ve ever seen.
To prevent the cubes from melting, the CNC router was kept chilled to a temperature of -7 degrees Celsius (about 19 Fahrenheit), and each cube took between 1-6 hours to complete.
