Please take all safety caution: wear eye protection, and do not launch bottle in somebody's general direction.
Our big launches were with a 1 liter bottle 1/3 - 1/2 of the way filled up with water. As long as there is a tight seal around the pump, you're good to go. More water than that and you'll get soaked. Any less and it won't go as far, but will sound louder.
