Slow Motion Video of Aluminum Powder Being Ignited in a Laboratory

As part of its “Aluminum Week,” the team at University of Nottingham site Periodic Videos shot slow motion video of aluminum powder being ignited over a bunsen burner. The experiment, which is repeated several times over the course of the video, alternates between appearing as a makeshift blowtorch and an all out cloud of flame. Aluminum powder is a primary ingredient in flash powder, a cocktail used to create pyrotechnic explosions.
