On my table is a water bottle, the usual blue-coloured plastic make that is in offices. Only, my bottle beeps once every two hours; it's cap lights up and blinks. It is not too obtrusive, and is a tiny reminder to drink up. The smart water bottle is a prototype from Briefcase, invented by Anand Damani and Mayur Tekchandaney. It is intended to "nudge office employees to drink water 16 per cent more". Essentially, using behavioural design to keep yourself hydrated.

In the course of the two weeks that I have had the smart bottle with me, I can safely say that it did its trick. I am not a slacker when it comes to hydration, but there are those days where you are glued to your screen, and you forget to drink water. The beep grows fainter gradually, but, I am sure Briefcase will figure a way to solve that. Every note from the dietician says "drinks lots of water". Lots, according to the Drink Water (named quite simply) is 2660 ml. This is a calculation based on my weight and age.
