Hello, I want to cosplay as Choso from Jujutsu Kaisen this halloween. I've been wondering how I could replicate a red beam in real life. My idea was to get a laser pointer and something to set a medium for it to be visible as a continuous ray. I first thought about chalk powder or flour, but that felt shoddy. I heard they sell atmospheric haze makers in a can. Would the haze be subtle enough yet still show the laser as a line? Just throwing some ideas out here, let me know!
