A meme shared on Tumblr and Reddit instructs people to mix household chemicals together in order to make a glowstick.
Except the instructions are lifted from a how-to guide for making a chlorine bomb out of common chemicals. This device overpressurizes its container and explodes. The explosion releases deadly chlorine gas which when inhaled, interacts with the water in mucus membranes to transform into hydrochloric acid. It causes chemical burns in the throat, eyes, and lungs. It has been used as a chemical weapon for just over 100 years, and was first introduced by the German Empire at the second battle of Ypres in 1915, and most recently used by terrorists in Iraq and Syria who were targeting civilians with makeshift devices such as the one described in this meme.
I’ve removed the actual instructions for the device because some people are stupid and might try to see what would happen if they made one of these.
Please make sure that if you see someone sharing this meme, you explain that it’s a trap.
