I have a few: refrigerate onions before cutting to avoid crying

To get a banana free from the 'stringy things' peel from the opposite end...that's what primates do.

To warm biscuits, pancakes, or other breads that were refrigerated, place them in a microwave with a cup of water. This keeps the food moist.

No more mosquitos! Place a dryer sheet in your pocket!

Reducing static: Pin a small safety pin to the seam of you skirt, dress or slacks. Slip won't cling to skirt or dress and panty hose won't cling to slacks/pants.

If you seal an envelope and realize that you forgot to include something, place the sealed envelope in the freezer for an hour or two. It will unseal easily.

Use hair conditioner for shaving your legs! Smooth!
