If you think a paintball gun set on “Rapid Fire Random” is a great way to decorate easter eggs, You Might Be A Redneck. (Apologies to Jeff Foxworthy.)
I colored these with a little spinning gadget that uses specially formulated liquid egg dye. It was the most fun I’d ever had decorating eggs: much more fun than dipping them, and I have no patience with the little crayon thingie. Naturally, when I checked the stores the next Easter, I found no sign that they had ever made such a thing.
Using standard food coloring didn't work nearly as well as you think it might.
