Rod Laver, once my teacher, now a friend and peer has been working on a new Playing Card act. After struggling with a cheap eBay card fountain he asked me if I could make him something to create an explosion of cards at the end of his act. An air cannon was my answer.
I’ve built a few air cannons but they’re never quite the same, they always have different requirements. I’ve briefly documented the process for this one below. There is a video of the results at the bottom of the post.
A quick test and I’m done.
