Fizzing and Foaming- Rocket Launcher

Our science experiment

by Emma and Brooklyn

Soda pop guns                       

Materials:

1.Plastic bottle.

2.100m white vinegar.

3.1 cork.

4.1 teaspoon of baking soda.

Questions:

How high does it pop?

Does the bottle explode?

Hypothesis:

We think that the cork will pop out of the bottle and go flying!

Experiment:

1. Fill the bottle with 100ml of vinegar
2. Put 1 teaspoon of baking soda into the bottle
3. Quickly slot the cork into the top of the bottle
4. Stand back and watch it POP!!!

   

   Results:

   Our cork went really high because of the carbon dioxide in the soda reacting with the vinegar which smelt really bad and it exploded as the pressure built up.

    The vinegar went everywhere.

 Conclusion:

Our chemical soda gun worked well.

The gas pushed the cork up high,causing the cork to pop out.
