The new office I work in has a classic Water Cooler with the big water bottles that you flip over. There is a tremendous improvement in this technology. In the old days, you opened bottle and you flipped the bottle over quickly, hoping, praying that you could turn the bottle over fast enough and aim properly so the bottle landed in the cooler opening and you didn’t spill the water all over the floor.
These days, the opening is sealed with a cap, and the cooler punctures the seal. You can turn the bottle over as slowly and carefully as you want. There is no fear of dropping the bottle on the floor and spilling gallons of water on the floor.
