To explore more delicate containers for my dioramas, I decided to try egg shells. I used a pin to poke holes in the top and bottom of an egg, and then used a screwdriver to make a larger hole at the bottom. I used the bulb of a turkey baster to push the contents of the egg out through the larger hole in the bottom.
I then bleached the inside of the egg and rinsed it with soap and water.
I used a dremel/engraving tool to make the hole(s), and then added the scene. I can light the egg from the hole at the bottom, too.
