"Good old Martha taught us that rather than buying those ridiculously expensive anti-slip mats for a rug, just turn it over and run a few lines of acrylic-latex caulk every 6 inches or so. Let dry and flip over and your rug wont be going anywhere!"
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!!!
