But here is the thing: they do last.
Or, I should say, they can last if you take a couple extra steps. Last year I skipped a critical step and they didn’t last. They done busted. I opened up my egg basket (and yes, I keep all my eggs in one basket) and this is an example of what I found:
The egg on the left came from a batch that I sealed with polyurethane spray, while the one on the right was sealed with two coats of Mod Podge on the outside and on the inside. That is the important part — the inside. Egg shells are very porous and they become more and more brittle as they dry out. If you seal the shell from the outside AND the inside, the Mod Podge will soak into the shell and create a web-like bond, strengthening the surface. The end result is almost like plastic. Delicate, but strong. Those eggs will last for years. The egg on the above right has survived eleven years and four house moves, and I can still drop it on the coffee table from 10″ up without a crack. Not that I suggest you try dropping your eggs, but you get the point — who knows how long it will last?!
I know what you are saying… OK fine, I get it, but how do I seal the egg shell from the inside?
Boom. Here it is:
Bear with me, this is going to sound more complicated than it actually is:
First create a sealant coat out of equal parts Mod Podge and water. You can brush it on the outside easy enough, but getting it on the inside takes some finesse. If you have access to an eye dropper, go for it, but if you have straws around that will work too –just insert one end of the straw in the liquid and hold your finger over the opening on the opposite end of the straw, creating a temporary vacuum that will allow you to carry the liquid to the egg. Then lift your finger off the straw to drop the liquid inside the egg through the top hole (this is very scientific). Put your fingers over both egg holes and shake away! Let the excess liquid fall out as it dries. As long as the shell is dry from the start, it will absorb plenty.
Cliff Notes Recap:
Insert watered down Mod Podge in the egg by any means necessary, shake it around, then let it fall out and dry. Whoop, there it is.
Treat your eggs nice and they will last you, well, a long time. Long enough to survive a thrashing from Lola, anyhow.
