If you wrap your celery in tin foil before placing it in the fridge it will last for weeks, and it will still be fresh and crisp when you pull it out! This also works for stored broccoli for 7 weeks wrapped in tin foil, and heads of lettuce for at least 6 weeks!
Wedding-day white teeth! My dentist actually told me about this. Use a little toothpaste, mix in one teaspoon baking soda plus one teaspoon of hydrogen peroxide, half a teaspoon water. Thoroughly mix then brush your teeth for two minutes. Remember to do it once a week until you have reached the results you want. Once your teeth are good and white, limit yourself to using the whitening treatment once every month or two.
