Chemistry in Pictures: Glowstick goo show and tell

As a demo for a science fair at Lawrence Intermediate School, in New Jersey, chemist Allen Jones combined oxidizers, reagents, and dyes in vials to demonstrate the chemistry behind glow sticks. He used the bright display as a springboard to teach participants about topics such as bond cleavage and the conversion of chemical energy to light by the dye. The vials were still glowing after the fair ended, and Jones snapped this photo before packing up.
