Sulfur and Black Soot Time Lapse

Making and Knowing Project

This time-lapse video shows the color of two mixtures of sulfur and soot black becoming lighter in color over time. The mixture of the three casts on the left is 11.5 g sulfur to two tiny spoons (using the spoon seen in Fig. 5) of soot black; the mixture for the three on the right is the same but half the amount of soot black. The camera took photos every ten minutes for about 50 hours. The video plays three photos per second, showing seven hours and 30 minutes, after which the casts stopped noticeably changing color.
