Step 1: Turn on the tap
Fill the top glass with ice water; the cold will make the glass molecules contract.

Tip
Add salt to the ice water to chill it faster.

Step 2: Switch to hot water
With the top glass still full of ice water, run hot water over the bottom glass, or place it in a few inches of hot water. The heat makes the bottom glass expand.

Step 3: Do the twist
Gently twist the two glasses; they should come apart easily.

Step 4: Adjust temperatures
Still stuck? Try colder water, or keep the bottom glass submerged in the hot water a little longer. Unsticking them can take anywhere from one to 10 minutes, depending on the glasses.

Did You Know?
One ton of glass consists of 1,300 pounds of sand and 380 pounds of limestone.

  1. I tried this technique and it did not work for me. I'm not sure if there was a "substance" (ie: pop, etc…) that didn't get completely cleaned involved here, but i couldn't get them apart. I just decided I had spent enough time dealing with it. Wrapped the two glasses in several grocery bags and got old betsy out (hammer) and just broke the bottom glass away from the top one – problem solved 😛
