Birthday Candle Experiment
Put a small amount of baking soda in the bottom of a tall glass. Add an equal amount of vinegar. Don't worry you won't be pouring this on your cake! Tip the glass toward the candle as if you were going to pour the liquid on it. Instead after a moment the candle will wink out.
So what happened?
The classic baking soda/vinegar mixture produces carbon dioxide, which is heavier than air and can be poured from the glass to put out the candle.
Neat trick and keeps your cake germ free!
