1.) Get Rid of Fruit Flies. It's amazing what you can do with common household items. A dish of cider vinegar on the countertop will get rid of fruit flies!
4.) Keep your cooler cool without ice packs. This tip is great for those times when you need a completely disposable lunch or if you run out of room for ice packs in your cooler. Freeze part of your lunch! You can freeze all kinds of things that you'd normally take in a lunch and by the time you get to eating/drinking them, they are thawed, but still cold. Freeze grapes, orange slices, almost any kind of berry, bottled water or other drinks and yogurt. You now have a healthy item in your lunch and it helps keep it all chilled to perfection!
