"I love how excited the students are when we do these labs."

Chemical reactions are fun to watch. Enjoy viewing some of the more explosive types in the STEM movie and then witness chemical reactions occur right before your eyes as the copper oxide coating on pennies reacts with an acid (vinegar). Witness the change at the microscopic level and then take your shiny penny and create malachite with some more fun mixing.
