My daughter emptied our dishwasher the other day and stacked some large Tervis cups together. I now have 2 sets of 2 cups with one cup stacked on top of the other and I cannot get them apart.

I've pulled and twisted and cannot get the cups apart. I'm guessing the cups were still warm/hot when she stacked them and either a vacuum was created or the cups expanded as they cooled sticking them together. This is weird and frustrating.

Put them in the freezer?

Try putting them in the freezer over night, then fill the inner glass with ice and set them in a sink that is semi-full of hot water to warm the outer glass only. I don't know if that will work but sounds like it might do something.

or put them in a bowl of hot water

Put them in cold water, (underwater) then twist and they should come right apart.

ice in the inner one, set the pair in warm water.

Since all reasonable suggestions are taken, perhaps try subtle application of high explosives?

Add water to the cup underneath. It has created a vaccuum effect. Filling the bottom cup reduces the suction.

This but only submerge the outer cup in hot water.

10mm...

The best bet is to heat the airspace between the cups. This should push them apart. Temperature Differential will help as suggested with a cold liquid in the top cup and the bottom submerged in hot water. The hot water would tend to expand the size of the lower cup and the air between the cups, while the cold top cup will shrink. With double walled tumblers it may prove difficult.

A soak in very hot water would probably work just as well really.

WD 40 works with glasses that are stuck together.

K-Y

The hot water outside / ice inside should work, but here is an alternate if you have a seal - a - meal or other vacuum food storage system that has a large polycarbonate cylinder tall enough to fit the stacked tumblers. Creating a vacuum outside the tumblers should pop them apart.

Spray them with a waterhose...it seemed to work for my grandmother whenever two dogs were stuck together

Seriously...I would just soak them in really hot soapy water and tap the bottom cup with a rubber handled kitchen implement while holding the top cup.

Hair dryer. If that doesn't work ....cinder block

Putting them in the freezer didn't work. Next I'll try the ice and warm water suggestion. If that doesn't work then.....tannerite.

Sigmonkey….why 10mm? I don't want to blow my house up.

If you've got an air compressor with a rubber tipped blower attachment try a shot of air between the two cups. The technique works with 5 gallon buckets but they bend a little. I don't think you'd have to get a lot of air between the two to break the seal.

You take them outside...
