Molecular Explosions

Favorite Trip Quote
Dad: "You may not know this, but when you get to high altitudes, pressure increases which causes explosions of toiletry and other packaged items."

Katie: "Dad, I may not have climbed a mountain before, but I have been in a few airplanes. I get it."

Example:
Gary figured this out when he went to open a new can of powdered milk when we were pretty far up the mountain. He was quite surprised when the powder decorated his sweatshirt.

Just to be acurate, the atmospheric pressure decreases as you go up in altitude which allows the air inside a sealed container to expand. Want to make sure your students understand correctly :)
