Scientists of LessWrong, I have Important Questions for you:
What would happen if Harry donned his invisibility cloak and stepped through the mirror?
(Physics)
Assuming CPT symmetry, Would the mirror universe be composed entirely of antimatter? Would the anti-nitrogen molecule annihilate with dust particles on Harry’s cloak, emitting vast quantities of gamma rays?
If so, would the cloak shield Harry from the gamma rays, or would they be “duplicated” the way visible light photons are? If the gamma rays are duplicated, the temperature of Harry would increase very rapidly. Does the invisibility cloak emit black body radiation? At what point would Harry be visible due to black body radiation alone?
If Harry is not annihilate, what is the simplest experiment he could perform to take advantage of reverse-chiral weak interactions?
Assuming the mirror permits electric fields to travel through it, what would the effects be near the surface of the mirror? Would electron on air molecules near the surface of the mirror be torn off and stick with their reflected positrons? Would the mirror become a giant capacitor? If so, how many coulombs of charge would it hold?
(Chemistry)
Assuming the mirror universe is not composed of antimatter, what sorts of fun activities could Harry do with stereoisomers? For example, what schedule 1 drugs could Harry obtain on the cheap?
(Biology)
Assume Harry starts eating in the mirror universe. What sorts of nutritional difficulties will he encounter? For example, would he be able to metabolize proteins? Carbohydrates? Fats? Nucleic acids? Are there any essential amino acids Harry will be missing?
Would the mirror bacteria and fungi be able to metabolize Harry? Who would win in a fight: mirror bacteria or Harry’s immune system?

Only metabolizing fats, glycerol, and the simplest amino acid, glycine. Everything else is chiral, including a hell of a lot of vitamins. Mirror sugars still taste sweet though. I have no idea if mirroring a protease changes its ability to digest protein (for all the good liberating mirror amino acids would do) but know nucleases and starch-degrading enzymes would be useless.
Though for energy alone he could also consume alcohol, acetic acid (think vinegar), and some ketones and aldehydes that are pretty nasty in large quantities but you can get some cellular energy from like acetone. Unable to get any of the essential amino acids histidine, isoleucine, leucine, methionine, phenylalanine, threonine, tryptophan, valine, or lysine.
Regular bacterial cell walls contain a few mirror amino acids produced enzymatically during wall production—mirrored glutamate, glutamine, and alanine. Not gonna be much. You could probably make about half the nonessential amino acids internally by drinking VERY VERY dilute ammonia (or thicker glycine) and eating fat/alcohol/acetic acid, and the other half of the nonessential ones by drinking VERY VERY dilute ammonia (or thicker glycine) and VERY VERY dilute acetone. Don’t quote me on that, amino acid metabolism is cellular witchcraft with a few rules of thumb to me compared to central carbon metabolism where I do my work. The acetone would also allow things like the production of carbs internally for the purposes of connective tissue renewal and the like faster than the weird still not quite understood in animals very slow production of sugar from fat breakdown products. Though your kidneys and liver would probably fail long before anything in this list was useful.
Levulose (mirror dextrose, as the names indicate) is a good non-caloric sweetener for this reason; it behaves for the chemical purposes of cooking exactly like dextrose. You can’t get it commercially, because it costs too much to manufacture (or so Wikipedia tells me), but it would be perfect if only it were cheap.
If the mirror universe was antimatter, Harry would be annihilated instantly because his feet are touching the floor, even if the Cloak could shield everything else.

Couldn’t he crawl?
He has to breathe.
