Warning: Don’t try doing this at home, or in fact, anywhere.
Laser (100mW Spyder III Krypton) burns black flash paper to ignite alcohol rocket bottles. They make fire, light, heat, and sound as they go off!
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.
