It comes as urine already in a little 2-3oz bottle. It comes with a little hand warmer, rubber band, and a heat sensor on the bottle. Heat it up in the microwave for 10 seconds or so, get the hand warmer on it with the rubber band (NOT on the side with the sensor) and throw it in ur skivvies or in your sock/shoe or even buy a wizzinator... The things to pay attention to are the temp (90-100) and that you don't pour all of the quick fix in. If you use the exact amount it fills it to the line on the bottle and that merits a red flag. Anyway, it is really easy and you will pass it with flying colors.
