Lava lamp experiment

We did a lava lamp experiment in class. I learnt that oil and water do not mix and when there was a chemical reaction the gas carbon dioxide was formed.

How to inflate a balloon

To do this experiment we needed:

• vinegar
• Baking soda
• Paper funnel
• Bottle
• Spoon 
•  How  to do the experiment

First we put vinegar into a bottle.

Next we used a paper funnel to put baking soda inside the balloon .

Then we attached the balloon onto the mouth of the bottle .

After that  there was a chemical reaction.  The baking soda and vinegar mixed together to make a gas called carbon dioxide.

The gas then  inflated the balloon.
