There's some interesting chemistry at work when a blazing black snake firework unfurls into its signature shape. Unfortunately the effect itself is pretty underwhelming, making it the forgotten misfit of every fireworks variety pack. This video spotted by Sploid takes that same concept and maximizes it to epic proportions.
For the experiment, veteran YouTuber NightHawkInLight lays a mixture of baking soda and powdered sugar on a bed of sand that's been soaked in alcohol for fuel. After it's ignited, the sugar burns and the baking soda produces carbon dioxide. The gas that's released inflates the ash into a fiery volcano shape that looks about 100 times cooler than the fire snakes you lit as a kid. You can watch the full experiment play out in the video above.
