Experiment:  Cork Rocket

Objective:  What will happen to a cork in the top of a bottle when you mix vinegar and baking soda together in a bottle?

To begin, Thomas measured out 2 oz of vinegar…

…and poured it into the empty bottle.

Next he measured 1 teaspoon of baking soda,

poured it onto a paper towel square, 

and wrapped it up.

After that, Thomas dropped the wrapped paper towel into the bottle with the vinegar.

He then quickly inserted the cork loosely into the top of the bottle.

The mixture of vinegar and baking soda quickly started to produce a gas indicated by the bubbles!

Thomas then moved back and we all waited for a quick moment…and the cork shot out of the top of the bottle!!

(We tried 3 times to catch an image of the shooting cork, but it was too quick!)

Conclusion:  As vinegar and baking soda mix, it makes a gas.  When the gas builds in the bottle, it blows the cork out!

You were well prepared and did a GREAT job,

Scientist Thomas!
