In reply to Jim Fraser:
Put it in an ice cube tray and pop it in the back of the freezer. The individual compartments are even the right size for each splurge you produce, so over a week or so, you should have enough for a rugby team. Not sure of the correct medical process to use it though, but I should imagine you could just insert it and let the recipients body heat do the rest.
You'd have to make sure that no one uses them as novelty ice cubes at a party though...
