About to Explode

No, don't be alarmed...this is not about our boys' after school hobbies. It is what you can find in your grocery bag... 

Many containers have a lid and then the top is actually sealed.  Hot Chocolate, Pringles, Nutella, are some that we have in our home frequently.  At Sea Level, these are just sealed containers.  But at 6200 feet elevation they are containers that look like they are ready to explode!

Before

 

I am amazed every time I take a lid off and see it! Can you see it in this photo? It is not flat from edge to edge...it is very tight and very round!

I bought some canning jars to make peach syrup..yum...and they even gave me the "fresh" sound when I opened them. 

Each time we have driven to the top of a 14er, we have had an empty water or Gatorade bottle.  So we closed it up at the top of the mountain and checked it at the bottom.  This is what happens: 


We want to save these and take them back to Washington with us on a visit. Will they crush more or stay the same.  Crazy!
