Smoking itself is injurious to health but lets be honest smoke does look cool. You may also have fancied about those cigarette/hookah smoke rings and other cool things you can do with smoke.
There is this neat little trick by YouTube user “noncents” telling about how to make smoke act like liquid. You would need 1 unfiltered roll up and a cold glass for the trick to work.
Don’t inhale the smoke just pull it into your cheeks and let it fall out your mouth along the inside of the tilted glass. Do not breath as you do this or it will blow it all away!
