I didn't really think the laser 301's were "that" powerful. However, it will burn very dark colored material, rubber, some plastic, leather, paper. I guess not really burning as much as smoldering and making it smoke It will burn, slightly melt the blue colored NERF darts. It won't burn my skin, although it will shine enough light through my flesh to see the blood vessels inside, and it does it without almost burning me like my 2500 lumen Powertac flashlight. Not bad for a cheap "5mw" laser..
