Japanese artist Haruhiko Kawaguchi took nearly 80 duos (most of them real-life couples) and trapped them in vacuum-sealed bags. The process called for the participants to pose and hold their breath for 10 to 20 seconds, the time it took to snap a few photographs.

Each couple needed about 5 liters of lube (at 10 times normal concentration) to ensure that their skin wouldn't burn in the process. Reportedly, only one guy pissed his pants during the whole ordeal.
