Okay, so. There isn't a lot to go on, if I'm honest. This looks more like an idea, and less like a draft. It may benefit you to run the idea past the Ideas and Brainstorming Thread, describing what you are thinking of, but not linking to your draft unless asked.
Euclid
I would say this object is Safe. Put it in a box, lock it, and leave it - it'll be fine.
1 meter by 1 meter by 1 meter box.
Generally, write measurements as such - 1m x 1m x 1m. Does the size of the box really matter, or will any box that's refrigerated and fits the plate do? If so, you don't need to include the measurements.
However, after food is placed on it, after being refrigerated for an hour, the food changes material into atoms of a seemingly random element on the Periodic Table, but retains its appearance. The food does not bond with anything until eaten, when it combines with the consumer's tongue and teeth.
The idea is a bit all over the place, with no real solid point. Why does it do that? How was this discovered? What happens when it 'combines with the consumer's tongue and teeth'? You have to remember that The Foundation doesn't know this information, so they have to find out organically, not magically. Additionally, there is no narrative to this - you need something to keep your readers reading! I suggest reading more Series III articles, where story-telling became a main focus of a good article. Think less of the object, and more of the story you want to tell.
Good luck!
