Jason has gotten the food from the fast food restaurants.

Week 1 [12/23/13]

Wendy's has grown white foam on it's side, while the other burgers grew no mold. however the cheese in all the burgers have "melted" as if the saturated fats in the cheeses have left, leaving them with only their unsaturated fats with are more liquid than solid.


The fries from Sonic and McDonald's are molding

Sonic's fries are molding with a darker variation of the white foam.

McDonald's fries are growing a different type of mold, it was greenish-white and it was growing just on the fry itself.
