This week Reactions is checking out some firework science. There's a bunch of chemistry that goes on when these guys light up the sky at night. From the sizzle of the fuse to the boom and burst of colors, this video brings you all of the exciting sights and sounds of Fourth of July fireworks, plus a little chemical knowhow. John A. Conkling, Ph.D., shows how the familiar rockets and other neat products that light up the night sky all represent chemistry in action.

𝍤 Pyro drones are transforming July 4th firework shows by launching pyrotechnics in intricate patterns with millisecond accuracy. These high-tech displays require extensive engineering, choreographed flight plans with 3D animation software and sophisticated GPS systems. But these massive shows aren’t without risks as crashing drones can be a real concern.

WSJ explores the technology behind how the quadcopter fleets are changing aerial displays.

𝍤 ❤ Each drone carries up to 6 pyro-charges. Normal fireworks save 20% for finale -- not possible with drones. Drones do not have cameras and only know own location. Redundancy in systems for safety is very limited. Separated so each drone is not directly above another, 6 1/2 ft bubble, operate within a geofenced area.
