Misuse of Lab equipment (part 1)

I'm doing lots of late night microscopy at the moment, and for some reason there isn't a source of cold drinkable water here in the evenings (they seem worried we'd steal the water cooler from the canteen if we could). So I decided I'd misuse some lab equipment.

Adam's Mark I water cooler is as follows:
1 bottle of tap water (quite warm for some strange reason)
1 ice bucket full of lab ice (no one ever cleans the machine so I'm not putting it in my drink)
1 rotary shaker (kind of swirls in a horizontal circle)
1 chair (shaker is usually under the desk, so I had to stand it on my chair to make space).

Switch the thing on at about 100RPM, and wait 5-10 minutes for nice icy cool water. (which tastes just like the Evian I bought earlier today....)
... ok, so it isn't a hugely exciting post, but I was pretty bored....
