A video posted to the Home Science YouTube channel shows the "strange chemical reaction" that occurs when pool chlorine is mixed with popular soft drink Coca-Cola.
For a few seconds, nothing happens when the two come into contact with each other.
However, moments later, bubbles can be seen violently floating to the top, ultimately pouring outside the glass in a "spectacular little explosion."
According to the creators of the YouTube video, the gas produces is actually poisonous, so don't try the experiment at home.
"The small amount of phosphoric acid in the Coke sets off a chemical reaction with the calcium hypochlorite, producing poisonous chlorine gas and a spectacular little explosion," the producers wrote on YouTube.
