How to make a homemade vortex cannon

Hello, homemade vortex cannon! Secure a tightly closed box, then add a narrow round hole at the end. Hit the sides of the box to compress the air inside, sending the air out with some force. Instant vortex ring. The Urn Science Show team at the University of Nottingham added smoke with a fog machine so that the vortex ring is visible as it travels across the room.
