Unless I’m greatly mistaken, these are the pipes that one uses to smoke ganja? I remember seeing these in little shops on my way home from school as well, and wondering what they were. Back then, I figured they were some special attachment to be used on taps. My curiosity continues unabated and I’m still wondering whether these aren’t illegal. If I’m right, they are…sort of.
I could be wrong, however. Does anybody know what these things are used for? I didn’t have the nerve to walk up to the shopkeeper and ask him. He didn’t seem perturbed by my taking photographs though.
