How to Put Out a Candle With Magic





Introduction: How to Put Out a Candle With Magic

About: I always liked making stuff and when my grandfather showed me Instructables I became an addict. I don't have any degrees yet but I'm working on my aeronautics engineering degree :-P

There are many ways to put out a candle, one of them is using vinegar and baking soda. This guide is a cool simple trick that will impress your friends and even might you teacher.

Step 1: Watch Video

Step 2: Materials

For this project you will need:


Baking soda.

A glass.

A lighter and a candle.

Step 3: The Trick

Start by lighting the candle.

Pour some baking soda into a glass.

Pour some vinegar over it (you'll see the reaction happening).

Now turn the glass over the candle without spilling the mixture and see the candle putted out.

Step 4: Scientific Explanation

1 NaHCO3 + 1 HC2H3O2 → 1 CO2 + 1 H2O + 1 NaC2H3O2

The reaction between the soda and vinegar is acid-base reaction that in this case one of the products is CO2.

Carbon dioxide is a gas that is heavier than air and has no color. This is why when we turn the glass the CO2 is being poured out without our notice, then separating between the flame and the oxygen and causing it to put out.

Step 5: That's It

    Now if only I could trap the gas for later use... oh yeah balloons :)

    I think that a test tube would work better, since CO2 is heavier than air, the air will "spill" out of the tube leaving only CO2 in it, also gas tends to leak through balloons, but if you do try let me know what went out :)

    It should be on the first step I'll check

    Cause it's a science experiment that might seem like magic..

    covering it is no trick. a kid could see that. However, using this might seem magical until those kids take science in middle school.
