Balloon Experiment 2

We wanted to find out if other liquids would blow up a balloon like the 

White Vinegar did in our first 

balloon experiment.

We tested 4 different liquids:

 Malt Vinegar, Milk, Sparkling Water and Coke

We made it a FAIR TEST by using the same glass bottles, the same colour balloons, 1/2 a cup of each liquid and 

3 teaspoons of baking soda.

The only variable we changed was 

the liquid.

Some of us thought the 

MALT VINEGAR 

smelt a little bit funny!

We put the liquid into the bottle 

using a funnel.

We put the BAKING SODA in the balloon by using a funnel.

We made predictions about 

what would happen.

Some of us thought the balloon 

would fill with gas 

and some of us thought it 

would not fill with gas.

We observed what happened...

when Lauretta tipped the 

baking soda into the malt vinegar.

We saw a chemical reaction. 

The baking soda and malt vinegar mixed together to create a gas called carbon dioxide. 

It bubbled up and the gas blew 

up the balloon.

 We did the same experiment 

but this time we used milk.

We made predictions about what we thought would happen.

This time the balloon did not fill with gas, it was floppy.

We did the same experiment 

but this time we used sparkling water.

We made predictions about what we thought would happen.

There was a little bit of a 

chemical reaction. 

The balloon was filled with a small amount of gas.

We squeezed the balloon 

to see what it felt like.

We did the same experiment 

but this time we used coke.

We made predictions about what we thought would happen.

 There was a little bit of a 

chemical reaction. 

The balloon was filled with a small amount of gas.

These are our results from out experiment.

We are wondering why the 

malt vinegar had the biggest

chemical reaction!
