#20: A New Kind of Water Fountain
These modern water fountains have been popping up everywhere in recent years. They’re pretty nifty. Many people carry a reusable water bottle with them when they go to school, work, or local stores. This water fountain is specially built to fit most reusable water bottles. You can place your bottle under the fountain, and it automatically refills it to the top.

Some of these machines even have a feature that tells you how many plastic water bottles you save by refilling your reusable jug. This is way better than trying to quench your thirst with those tiny water fountain spouts. However, the old-fashioned spout is still installed if you don’t have a reusable water bottle. You know, for old time’s sake.
