Separate two stacked plastic cups to restore their usefulness.

Stacking plastic cups within other plastic cups may seem convenient, but this space-saving storage method doesn't necessarily save time. Using your bare hands to force apart two plastic cups that are stuck together can become a time-consuming and frustrating experience. Trapped air and moisture in the spaces between stacked plastic cups create suction, which forces the cups together. Plastic cups become harder to separate the longer they remain stuck together, but you can promptly force apart two stacked plastic cups using basic techniques.
