Two ways of dealing with tear gas grenades from comrades in Turkey: Either submerge them in water. Make sure you can close off the container cause the gas will still spread for a while. Or throw them in the fire so the gas burns off before it can spread.
“Empty your mind, be formless. Shapeless, like water. If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot, it becomes the teapot. Now, water can flow or it can crash. Be water, my friend.” (X)
