I've had them for over a year. Gross, right? Nope. They're blown-out eggs -- eggshells.
I've flipped the eggs over in the picture above so you can see the holes.
These lightweight eggs are full of potential for Easter decorating. Most basically, you can dye them just like regular boiled eggs. Here are a dozen I did, using a marbleizing technique I discuss below:
So how does one blow out an egg? A lot of people use the two-hole method, where you poke a hole in each end of the egg and force the contents out with your mouth or with a bulb-like contraption.
I prefer the one-hole method, because who wants two holes in your egg when you could just have one?
I use this little tool, which is made specifically for one-hole egg-blowing:
You poke a hole in the egg with the little green drill, and then you carefully force air into the hole with the yellow hand pump. The air creates pressure inside the egg, which forces the contents out the same hole. You can buy the egg blower here for $8.95.
After rinsing and drying your eggs, you can get to work on your masterpieces.
