A better way to keep celery fresh (and it works for Romaine lettuce as well) is to wrap it with a damp paper towel and then put it in a plastic bag with as little air as possible and refrigerate.
Popcorn will keep longer if stored in the freezer.
Keep brown sugar wrapped in another plastic bag in the freezer to make it last longer without hardening. Take it out to thaw about 15 minutes before you need to use it, then return the remaining portion to the freezer.
Red wine spillage?
If you spill red wine on a carpet, pour white wine right over it. The white will neutralize the red wine. Follow with light soap and water and blot with a thick towel.
