I think these would be pretty cool decorative beer bottle/glasses to have lying around and a definite conversation starter. You’re creating from something you’d throw away anyways. It’s recycling and re-purposing at it’s finest.
Warning: this stunt involves sharp edges, breaking glass and fire. But if you’re careful, it could also involve fun.
TURN BEER BOTTLE INTO DRINKING GLASS
STEP 1:
Pick a brand with a sturdy but attractive bottle. (Try Grolsch or Darling Brew’s dumpie-style bottle. Corona’s also good, because the bottle is especially thick.) Tie a string tightly around the empty bottle just above the label.

STEP 2:
Slip the string off and soak it in lighter fluid. (Keep your fingers dry!)
STEP 3:
Put the string back on the bottle and light it. Hold the bottle horizontally and rotate it so the flame spreads. Wait to hear the bottle crack slightly, about 10 seconds.

STEP 4:
Pour cold water on the string. The top of the bottle will fall off.
STEP 5:
Sandpaper the edges until smooth.
