Just like that. The ice in the first cup will expand, pushing the first glass upward using some sort of Scientific Force.



Now you may remove the second cup from the first. If you have used plastic, as the instructions stipulate, this will be easy. If you've used glass there will be little shards of glass mixed in with your Archimedes Cube and you will drink bitter sorrow.



Bonus! The ice cube from the second cup can be given to someone less cool than you. It is a fully functional ice cube.
