You think you’re ready for the GED science test? Really? REALLY? Here’s a “POP” quiz question to test you out.

POP-POP, FIZZ-FIZZ

So…here’s what happened.

I took a “POP” bottle, and into the bottom I put some vinegar and water. Then, I took an empty balloon and put some baking soda in it.  I attached the balloon to the end of the bottle, and then poured the baking soda from the balloon into the bottle, so it mixed with the vinegar and water.

Pop-pop! Fizz-fizz! Millions of bubbles started to appear! And my balloon started to BLOW ITSELF UP!!!

So, here’s your “POP” quiz…what made the balloon blow up?

A) The air inside the bottle was pushed out by the baking soda.

B) The baking soda and vinegar caused a chemical reaction that released gas, which blew up the balloon.

C) The baking soda and vinegar caused an explosion that created extra air, which blew up the balloon.

D) The air inside the bottle was pushed into the balloon by the bubbles created by combining baking soda and vinegar.

So, what’s the scoop? Which is the most “POP”ular answer?  Tune in next time to find out what the science is behind this question.
