Scott A. Stevenson of WorldScott used a 100mW Spyder III Krypton laser to light black flash paper inside of ten alcohol rocket bottles. When ignited, they made bright flames and whistling sounds. The video, which includes slow-motion footage, was recorded at the Cremerie de Paris.
Several cameras were used to capture the alcohol rocket bottles as they shot out flames from their tops and whistled. Two slow motion cameras show the action in finer time detail. A few bottles produce beautiful blue flames inside as the fire descends down the length of the bottle.
