DVD Burner Laser
Warning: don’t mess with lasers. You might think everything is fine, but later you start seeing spots. It’s possible that your eye doesn’t respond fast enough to intense laser beams leading to eye damage. So don’t do anything stupid with lasers.

Really, there’s not more more to say. The pressure waves from the low frequency sound prevents the oxygen from getting to the fire.
