Will Fire Pop a Balloon?

Student Demo By:Alyssa Brown

How This Grand Presentation Was Thought of.

One day, I was just sitting around thinking about what I should do for my student demo and it just hit me. I remembered when I went to a birthday party for my cousin and she was turning five years old. I remember that we had a water balloon fight. A few minutes before it was time to sing happy birthday, my aunt set the cake on a table so it would be ready. Somehow, one of the balloons didn't get any water in it and some one blow it up. Well, I was sitting at the table with the cake, playing with the balloon and it got to close to one of the candles and it..... So now since you know that the balloon pops, what do you think could stop it from popping when put on top of a flame?

The Science Behind It

The science behind of the non popping balloon is heat transfer. When the water gets close to the heat, it absorbs the heat from the flame. So the rubber on the balloon doesn't get very hot which doesn't cause it to expand, which doesn't cause the balloon to pop.

Material

A source of water

2 balloons

1 lighter

1 candle

1 funnel

1 measuring cup

Procedures

1.) First, I will blow up the first balloon

2.) Then,I will put 4 1/4 of a cup of water in the second balloon and then blow it up

3.) Next, I will light the candle

4.) Then, I will put the first balloon over the flame

5.) Finally, I will put the second balloon over the flame

If I Were to do This as an Experiment

Testable Question- How does the amount of water affect how burned the balloon is?


Hypothesis- If I increase the amount of water, then the balloon will have a bigger burned spot on the balloon.


Independent Variable- the amount of water


Dependent Variable- How big the burned spot is on the balloon.

Now go to Kahoot!

The carbon was deposited on the balloon by the flame, and the balloon itself remains undamaged. The chemical element of atomic number 6, a nonmetal that has two main forms (diamond and graphite) and that also occurs in impure form in charcoal, soot, and coal.
