Peeps in a vacuum chamber

Chief Scientist, Carl Nelson puts Peeps in a vacuum chamber to find out what happens when the air is removed from the fluffy candy.
The balloon and Peeps expand as the air pressure in the chamber is reduced by the vacuum pump. Peeps contain millions of tiny air pockets inside the gelatin/sugar mixture they made of. As the air expands inside the Peep, it pushes against the walls of the air pockets and eventually tiny rips and tears form between the air pockets that allows the air to escape. Once the air stops flowing out of the peep, the force exerted on the Peep relaxes a bit and it begins to slowly shrink. Allowing air to rush back inside the chamber further crushes the Peeps as the air slams into them.
Christina noticed that the Peeps felt cold when touched. From a thermodynamics perspective, the tiny air pockets inside do Work as they expand. The energy used to do this Work on the walls of the pockets reduces the internal energy of the air inside the peep and it's temperature drops, thus cooling the Peep.
The shaving cream grows large for the same reason as the Peeps. When the air is suddenly returned to the chamber the foam is much more dramatically crushed since it has a much weaker physical structure than the gelatin/sugar mix used in the Peeps.
Imagination Station, Toledo's hands-on science center, is a vital non-profit organization that is an integral part of Toledo's economic, educational and social landscape. Imagination Station provides a critical layer of science enrichment by serving as an educational partner for teachers, schools and parents. It's with a thoughtful blend of exhibits, experiences, education and excitement that Imagination Station is inspiring future generations of scientists in Northwest Ohio. With hundreds of hands-on exhibits and demonstrations, Imagination Station delivers a multi-sensory experience that's as fun as it is educational.

Fun fact, elasticity is the property a material has to go back to its original shape and size after being stretched. Distensibility, is the ability of a material to be stretched. Just to keep CS Carl Nelson on his toes :)

[@spyderhyatt]

where the pressure differences do play a big factor and why the shaving cream behave that way I believe at the end the reason it exploded is because the air coming back into the chamber comes from the bottom at a very fast rate and shaving cream is so light that the force of the air shoves it into the top of the container

Air molecules are rapidly moving around inside the peeps. The rapid movement builds up heat energy. When air molecules escape the peeps the heat energy escapes with the peeps, and they become cold.

It then punishes you by bringing the wicked cold from the north, the burning heat and humidity from the south, the crime-rate from Michigan, the flatness of the midwest, the difficult terrain of the Appalachians, the traffic of a major city without actually having a major city, the storms of Tornado ally, the mosquitoes of Florida, a education system that couldn't find its own ass in the dark without a flashlight map compass and trained guide, and track housing... track housing everywhere...

The shaving creme behaves pretty similarly to the human brain when exposed to the vacuum of space. That's one of the reasons even if you get a person back into the ISS after being exposed you have to be very careful you don't deflate their brain.
