Demonstration videos and the human touch

ChemToddler

This is a collection of nearly 50 video clips which demonstrate a wide range of reactions and laboratory techniques. Ignoring the background music, there is much to enjoy here with well-filmed clips that typically last for about two and a half minutes. 

Some classic experiments are shown, including demonstrations with liquid nitrogen. The thermite reaction is performed using the flowerpot method so that the viewer can see a stream of molten iron (shown in slow motion) emerging from the hole in the base of the flowerpot which falls onto a tray of sand below.
