Designed by Michael Tatschl, Sascha Mikel, and Martin Schnabl, this watergate concept has now been materialized into a product.
The Watergate is using liquid called “water” as the psychological barrier. The reason behind: people dislike getting their clothes wet.
A good thinking is that, if something urgent happens, people can run through the watergate without having to pass any steel gate.
People in wheelchairs or carrying luggage can easily pass through them. Indeed a clever design.
