The pickle jar didn't pop when it was opened because the pressure inside the jar was equalized with the pressure outside, preventing the popping sound.
During packaging, a vacuum was created inside the jar, pulling the button in. When the jar is opened, the vacuum is released which allows to button to return to the "popped up" position.
The pop-up tops on jarred food are there to tell you if the item had been previously opened. These can fail, but a good rule of thumb is to return the item if that is "popped-up" before you open it.
Pop and pickle juice
A can of Pop Pops when you open it because the pressure in the can is released from the can when it's opened.
the soda pop fizzes when opened becasue the carbon dioxide is being mixed with oxygen with causes a reaction like you have seen in the soda pop
I use a sealed cookie jar and scoop it out as needed. * Popcorn can also be stored in the freezer.
There are a lot of stories about cash to be made from the collecting and recycling of aluminum pull tabs from soda cans. Most of the stories are myths, as detailed here: http://www.squidoo.com/pulltabmyths Ronald McDonald House continues its national collection program through schools and civic organizations, for which the charity earns about $8000 annually.
In order to keep the pop carbonated (fizzy), there must be air pressure built up in the can. The pop or whoosh you hear when opening a can is that air pressure escaping.
