How to Cut Glass Bottles with a Simple Coin: A Retired Glassmaker’s Trick

Tie the string tightly around the bottle at the exact spot where you want to cut.

Soak the string in rubbing alcohol or nail polish remover for better combustion.

Light the string carefully and let it burn around the bottle’s circumference.

Once the flame goes out, immediately submerge the bottle into the bowl of cold water. The rapid temperature change causes the glass to crack along the heated line.

If the glass doesn’t separate fully, repeat the heating and cooling steps gently until it comes apart.

Smooth the sharp edges with sandpaper or a glass file for safety.
