Celebrating With Green, Eye-Catching Sparklers | Headline Science
Sparklers can be a lot of fun — glimmering, fizzing and spitting out arcs of light from handheld sticks or tubes on the ground. But the metals that they’re usually made with limit what the sparks can look like. Now, researchers in ACS Omega report that rare-earth metals in alloy powders can produce flashes that shift from golden to green and continuously branch.
