Happy Independence Day! Do you know what chemicals are responsible for the popping, snapping and crackling sounds of fireworks? Hint: One is less friendly than the other. How about which elemental compounds produce colors in fireworks? Learn more in these short videos by ACS Webinars! Some of the content (especially in the colors video) is a bit technical, but I am confident you’ll learn something interesting no matter what you science education is!
*note* There is a typo in this video for one of the chemicals responsible for sound.
