Footage of an interesting "experiment" during which a man blasts holes in a sheet of ice with two massive fireworks. <br /><br />The filmer drills two holes in the thick sheet of ice, then sets alight two massive fireworks called the "Big Boy" and the "Cobra 8" in close succession. <br /><br />Both emit powerful blasts, breaking through to the water below and leaving plumes of smoke hanging in the air. <br /><br />"This is one of my best explosion experiments!" the filmer said.
