Whether it’s a lack of time, money, or materials, constraints (whether externally provided or self-imposed) are often responsible for some of humanity’s most creative moments. As part of a Valentine’s Day project for a friend, Steven Bridges decided to create a romantic card trick, but with a catch: he had one hour to conceive of and rehearse a trick from scratch.

He limited himself to an hour mainly because he simply didn’t have that much time to put a video together for his friend. But what started as a happy accident has become an interesting lesson in flexing your creative muscles to rapidly develop ideas and see how well they work. You can check out the results from his “magic jam” in the video above, where he takes a mixed up card deck and makes it more “romantic” by transforming all of the black cards into hearts. Pretty impressive stuff, especially considering how quickly he put it together.
