Maybe you’ve mixed baking soda and vinegar together to watch them foam, but you’re missing out on one of the products of the reaction.
Don’t let anyone blow out the candles after dinner. Do it with this tried and true chemical reaction.
Place at least 2 tablespoons of baking soda in a clear cup.
Add 1/4 cup of vinegar.
Watch it bubble as the carbon dioxide is released.
Carefully pour the gas onto the candle, no liquid needed.
Poof! The candle flame is out.
Can you use different vinegars?
How many candles can your extinguish with one reaction?
Vary the amounts of the baking soda and vinegar, too.
Can you pour the glass into another cup and then use it?
