You may have seen people do this trick on television or even at a party, but making your own liquid smoke in a glass definitely isn’t as hard as it may seem. According to YouTube user “noncents”, all you need is one unfiltered roll up and a cold glass. Video after the break.
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.
