Hey there,

I'm high above the clouds right now somewhere over Ohio on my way to Chicago while writing this.  Since we have been talking a lot about air pressure, I decided to buy a bottle of water before we left the airport to use it as a demonstration about air pressure.  While in flight at an altitude well over 25,000 ft I opened the water bottle and drank about half of it.  What do you think the bottle will look like when we return to ground level?  Could you use what you know about air pressure and altitude to explain what will happen to the bottle water?  Later today or tomorrow I will update the blog with a picture of what happened to the water bottle to see if you prediction was correct along with an explanation for what happened.  Have a great night, check back soon for any updates about my experience at the National Science Teacher Convection in Chicago!

Sciencerely,
Mr. Botti
