When people think of chemical reactions used for show, they normally think of those that produce explosions or fire, or solutions and gases of pretty colors. However, the chemical reactions shown in the videos below produce structures that emerge from the reaction like tentacles of a being from another dimension or alien edifices.
NileRed made a YouTube video that went viral in 2017, and which I have mentioned before in my blog. This is a video of the amalgamation reaction between mercury and aluminum. The reaction takes place slowly, so it was sped up for the video. If you want to skip ahead to the emergence of the first structure, it takes place around minute two.
In the next video, also by NileRed, the reaction is more impressive as it takes place in real time. This is the so called Pharaoh’s Serpent, which used to be sold as a firework in Germany until it was banned due to the highly toxic compounds that it generates. Below is the short version of the video. If you want the long version with all the explanations of the complex chemistry that is going on, you can find it here.
The last video is by the folks of Home Science where baking soda heated with sugar produces an entity called “The Black Fire Snake”. Unlike the two videos above, this one has the advantage that this is something that you can try at home because it doesn’t involve or generate toxic compounds (as always be mindful of safety when using fire).
