Get tea faster to drinking temperature

Who does not know it? We are looking forward to a nice tea, which has pulled well, takes with pleasure a sip and ouch! Tongue burned.
It always annoys me that the tea takes forever to cool down.
Put in the fridge is not good, harms the device.

Simple solution:
Pack ice cubes in the tea. Stir briefly and viola the tea has cooled. Since the dice are made of water, there is no change in taste, and depending on how hot you like the tea, you do more or less ice cubes, are well portionable.

Bottom up! (Or what you say at the tea party :))
