The supplies are simple: vinegar, oil, and food coloring (well, and hard-boiled eggs, of course). I followed the instructions from this website. And it wouldn't be complete without step-by-step pictures, would it?
Aren't they pretty? I was tempted to stop at this point, for fear we might ruin them! :)
Once Rascal woke up, he was drawn to them like a magnet, making my photography session quick and painful ;)
A-ha! We have contact!
Needless to say, we will be eating these eggs sooner rather than later, as they all suffered some major damage after being investigated by Rascal (no name ever seemed more fitting!).
I think they turned out pretty cool. I think it would be really neat to add this technique to Easter egg decorating next year (I'm thinking some pinks, purples, yellows, greens). If you decide to try this yourself, make sure you follow the instructions on the website to create "whirlpools" in the cup before dunking your egg. This whirling, swirling action is what makes your egg look "earth-like" rather than an all-blue egg that was dipped in green. Found that one out through first-hand experience (patience is a toughie with 3 year olds!).
