Introduction
Do you ever wonder why you can only blow so much air into a balloon before the balloon bursts? Or why a volcano erupts and shoots gases, dust, and molten rock high up into the air? This activity will allow you to explore pressure changes similar to these in the safety of your own classroom! Be sure to wear your safety goggles whenever you work with chemical reactions — this activity is a BLAST!
Objectives
- Record what happens to the air pressure when you combine vinegar and baking soda in a plastic water bottle.
- Find out what happens when you mix different amounts of vinegar and baking soda together.
