Mic is reporting the meme above which purports to make glow sticks actually produces a chlorine bomb.
This bomb could be lethal. Chlorine can severely burn skin, eyes, mouth and lungs. It was used as a chemical warfare agent in WWI.
TO BE CLEAR: there is no evidence who did this. I tend to think Trump supporters or anti-Semites (is there a difference?) rather than Hillary supporters.
Please spread the word.
NOTE: Mic and Crooks and Liars reproduced the meme in its entirety so I think the horse is out of the barn about editing the image to hide directions.
I apologize for the poorly crafted earlier diary which I will now delete.
