[Open/Close] One-touch transformable coffee house

During the 52nd Venice Biennale, the famous coffee brand, illy, unveiled a futuristic pop-up coffee house to the public. Beside what appeared to be an abandoned shipping container, there was a simple button. Upon touching it, surprisingly, the container transformed into a fully functional and elegantly decorated coffee house. It was truly amazing! The only drawback was that the entire coffee house was open-air, including the restroom. Another concern B.H had, and found perplexing, was whether the water in the toilet would spill out when it transformed back into a container.
