Air Blaster Haunted House Effect

2020. As part of Totally Legit’s Mask Maze at Covid House of Horrors, I created this motion-activated air blaster effect to “cough” on participants as they navigated the maze. This involved automating the firing of an off-the-shelf air vortex cannon toy. This device was painted matte black and hidden from the audience. It was activated by a passive infrared motion sensor and accompanied by coughing sound effects. It performed well without incident for the two-week duration of the show.
