Friday night science

Here's a fun party trick. How can you extinguish candles without touching them?

Put some vinegar in a jug and add in baking soda. This makes carbon dioxide that can be "poured" over the candles. And, poof! They extinguish.

The CO2 is heavier than air so not only does it stay in the jug but you can then pour it over the candles starving them of the oxygen they need to burn. It's fun, give it a try. Amaze your friends.

    wouldn't water do the same thing? or even a wee bit of air? sounds like a sloppy way to put out candles

    It's just a trick that makes it seem like nothing hit the candle and suddenly it's out.

    This is great, I think I will try it at Susannah's as she usually has lots of candles burning. P
