A company called Urilift makes popup potties. And yes, that is exactly what they do.

Many cities are faced with the problem of public urination. Because there is a lack of public toilets, the night time bar crowd often step into alleys or along side of buildings to relieve themselves. Such actions not only create a smell, they also damage property. So, to help curb this problem, cities are installing popup toilets on the city sidewalks.

These public toilets remain below the side walks during the day when the streets are the busiest. And, they look something like a manhole cover. But, at night when the bar crowd arrives, these toilets spring forth from their hiding place in the sidewalks.

One unit, for example, is 3 feet in diameter and provides three urinals. Another is oval shaped and provides a single toilet.

All and all, they are intriguing but I wonder if they are practical. I guess time will tell.
