Some science activities make kids stop what they’re doing and stare in awe. This is one of them. At first the jar looks calm. Just oil floating over water. But then the color begins to fall. Tiny glowing streams drift downward through the jar, stretching, swirling, bursting apart like fireworks underwater. Under blacklight, the effect becomes even more dramatic. The colors begin glowing brightly under blacklight, and the movement becomes slow enough for kids to really watch the reaction unfold. This glowing fireworks experiment is simple to set up, incredibly captivating to watch, and perfect for summer science play, glow activities, or 4th of July learning fun. If you love hands-on glow science, be sure to explore our glow activities for kids and oil and water experiments collection for even more glowing reactions and liquid density fun.
