How Long Before an Egg Starts to Stink?
I know this sounds odd, but my kids want to know what rotten eggs smell like. (We were learning about volcanos and the smell of sulfur in the air, and it was described as smelling like rotten eggs.) I took an egg out of the refrigerator and am keeping it on the counter. How long should I wait before cracking it open? I want a horrible, strong smell. :)

Years ago there was a related question, How long can eggs be unrefrigerated before becoming unsafe to eat? . In that one, we're looking at how long are they safe (which means a very low probability of them being spoiled). But one of the answers links to an experiment from the 1970s by Mother Earth News.
In the article, they mention that they abandoned the unrefridgerated eggs (both store-bought and fresh laid) were still edible (but not great) at 90 days. But another month in:
By June (120 days after the experiment was begun) all the supermarket and all the homestead control eggs had gone completely rotten.
But not to worry, you don't have to wait 4 months:
Our experiment was set up on February 4, 1977 and was designed to run for a full year of regular monthly "look, sniff, taste, and texture" tests. It very quickly became apparent, however, that some of the "preservation" methods we were trying were worse than no attempts at preservation at all. The eggs (both fertile and unfertile) buried in both the wet sand and sawdust looked bad, smelled bad, had lost their taste, and had runny textures just one month after being "preserved". Even the control groups — eggs which were just allowed to lay out at room temperature with nothing done to them — were better than that. Conclusion after only four weeks: Trying to store eggs in either wet sand or dry sawdust is counterproductive. Forget it. Anything else — even nothing at all works better.
30 days might not be enough to get that really horrible smell. I'd probably go for 45 to 60 days in wet sand or sawdust. I have no idea if playground sand would be better than sharp sand for this, but I suspect that if you're doing this at a colder time of the year, you might want to give it a couple of weeks past that, just to be safe.
You can also pack up a dozen eggs, and then after 30 days (not weeks), check one. Then again every week or two until you get what you're looking for.

The Bottom Line With proper storage, eggs can last for at least 3\u20135 weeks in the fridge and about a year in the freezer. The longer an egg is stored, the more its quality declines, making it less springy and more runny. However, older eggs are still good for several uses.Can eggs start to smell?
When eggs spoil, they begin to smell bad, and the yolk and egg white may become discolored. Cracked or slimy eggshells can also be a sign of bacterial contamination.Can an egg be bad and not smell?
If you do test an egg by placing it in water, you can still crack it open to see if it's a bad egg. When you crack it open, look for other signs of discoloration or a sour smell. A fresh egg doesn't have a smell, but an egg that is going bad smells like sulfur.Why does my egg stink?
There is frequently the odor of sulfur. This is due to a reaction between traces of iron in the yolk and sulfur in the white. It happens only when the eggs have been overcooked. Perfectly cooked yolks are moist and deep orange.What Happens to Your Body When You Start Eating 2 Eggs a Day
