I recorded a video but during it I found something cool a cool idea you coudn't see the smoke good I Dont' think in the pitch black the night vision light isn't strong enough to catch it I think but I took my flashlight that makes a perfect circle it's a signal light it shiens for miles in a very small light powered by 1 AA battery it's awesome and it does on/off automatically too so you can leave it to get rescused anyway yeah it's cool and IK use it for uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh oh yeah it makes the smoke show up but since the beam is concentrated like a cone but like a flashlight/laser pointer hybrid but with an LED light, shine that shit and it looks so cool
