A few years ago I met Al Stahler in San Francisco at a Maker Faire like event. Al is the creative genius behind the "Fire Ball Gallery" (https://fireballgallery.com/). Al told me about one of his earlier projects called an "Airzooka Arcade" and the moment he described it I knew I had to make one myself.
The Airzooka is one of my favorite toys. It requires no batteries and is tons of fun. It shoots a vortex of air a long distance. The arcade has a supply of theater fog that the user can suck up into the Airzooka and once the elastic is released, the user can sing a ring (donut) of air flying through the air toward the target (helium balloon).
I built my Airzooka Arcade for the 2017 Charlotte Mini Maker Faire. I exhibited with my friends from Asheville Makers. To my delight, the Airzooka Arcade was a huge hit with both kids and adults. Check out the video below.
