Smokin,
Any soft structure, in 1 bar pressure (surface of earth) with sealed cells and molecules with spaces between will expand in a vacuum with the space between being less. As the one bar pressure returns (release of the vacuum) the cells and molecules return to normal and the spaces between will open up drawing in whatever is around them - marinade in this case. Using 20-30 minutes I have vacuum marinaded many a steak and it has all the marinade I want in it. Make sure you get the full 24 inches of vacuum (a full cycle). You can demonstrate this with a damp sponge or marshmallows in a vacuum canister.
If a person in space, is outside the spaceship and loses the pressure in their space suit he or she doesn�t implode, they explode. You ain�t going to get the Myth Buster to check that out.
