Here are the results of our Mc Donalds experiment to date.
On February 3rd we put 1/2 of a Mc Donalds double cheese burger in this tray. We set the tray up high on our dish cupboard. ( we have cats!) So here is what it looked like on day one. I had to kinda squish it into the tray to make it fit.
Here it is one week later. The white stuff on the burger is bread. Its smaller and lighter. Has no odor and no detectable mold.
This is 23 days from day one. Much smaller. Very light weight. Hard as a hockey puck! NO detectable mold. NO odor. ICK. We will continue to leave it on the shelve and check back from time to time.
