Tired of time-consuming, drink-diluting ice cubes? How about a pill which, when dropped in water/beer etc, cools it to a refreshing temperature in seconds. Perfect for hot days, picnics etc. It'll work by having two chemicals separated by a thin membrane, which breaks when wet. The chemicals react endothermically,
taking heat from the environment (the drink). All the products must be gaseous, insoluble in water and non-toxic. Also useful for high jinks involving public baths.

Drop in some solid carbon dioxide or liquid nitrogen (77 Kelvin). Done this before in the lab. Cold!!!!! |

Funny story, Peter: I *did* bring some home from my undergrad lab one day -- I had to wrap it in a few coatings of paper towels, and then crammed it into my coat pocket. Since it was pressed right up against the outside of my jacket, I had this square of frost that had developed. Warranted some strange looks. |

Words of warning: don't try and make your kitchen into an 80's rock concert video -- my housemates and I placed several of these CO2 chunks into a huge pot of boiling water. We were midway up our shins in opaque gas. |

Another strange trick is not putting liquid N2 into, say, a Coke, but pouring the Coke into the N2. You'll get some funny shaped Coke-ice chunks. |

A quick wat to create a cold drink from a hot drink eg hot coffee/ chocolate, depending on the weather, the person, etc. Great in small restaurants, aircraft, etc. |

Perfect for high heat index days! Brings a whole new meaning to: "Take a chill pill." |

Well you can already buy those plastic things you put in the fridge that you can put in your drinks to make them cool and not dilute the drink.
I however like the idea of a small tablet. I like the idea of so many practical jokes that could be played hehehe!!!
If you every find or invent one tell me I want to know. |

Geez, I was hoping for a pill that you take in order to successfully fake a cold so that you can get out of work... |
