you all have a good summer? (Or good winter, if you're on the southern side of things?) I'm sure there are several crafty things you could do with them; but my suggestion would be if you wouldn't ingest the eggs by eating them, why would you put them on your skin to be (at least partially) ingested that way? That said, the egg tempera would be really interesting to try. Glad you're back. I was going to suggest blowing the eggs and using the shells for something crafty, but Pennywise got there first. Isn't there a way of testing the alcohol content of beer using an egg? Although that would only use one. And there's a cool thing you can do using vinegar to dissolve the shells of whole raw eggs -- you end up with a dangerous bouncy ball, basically. Dangerous because it's liable to burst at any time with hilarious consequences. Do you not want to put them on the compost heap because of the contamination risk, or just because it seems like a waste? I am really happy to see you've come back! I have learned endless amounts of helpful tidbits through your site and it keeps challenging me to find new ways to reuse or repurpose in my everyday life. Thank you! Although this isn't using MANY eggs at once, it does allow for constant use/reuse of shells: as a natural drainpipe cleaner and food debris catcher- Keep a couple of crushed eggshells in your kitchen
