Has your champagne lost its fizz after you've popped the cork open? If so, don't dump it down the drain and throw your money away. Revive the bubbles in your champagne by dropping a raisin or two into the bottle. The raisin's ridged surface will attack the last gasps of carbon dioxide left in the wine and will be released as bubbles. This trick will bring back the sparkle to your champagne or wine that was opened two or three days ago. Go ahead and give it a try!
