What I came up with was this Eggcellent Night Light. It's minimalistic. It looks modern. It also shares some creepy Pagan relic "lunar" qualities.
(1) large white egg
(1) mint tin box - just the bottom half
(1) double AA battery pack
(1) white LED 3+volts
(2) AA batteries
(1) slide or push switch with two leads
(1) black paint or black spray paint
-metal punch or drill
Step 1: Let the hollowing commence!
If you are not confident with yourself in guesstimating where the bottom of the egg is, take a small piece of paper, color it with colored chalk, and place the egg upright on the paper. The chalk should mark where the utmost bottom is.
Use an awl or small screwdriver to tap/carve a hole at the bottom of the egg. Once a tiny hole is made, start tapping along the circumfrence of the hole to make it larger until the hole reaches 1/4in in diameter.
Due to pressure and surface tension, the yolk and white of the egg doesn't just come gushing out. I found out that the most efficient way is to stick a chopstick in the whole and just move it in and out to let the innards leak out fairly quickly.
Rinse the inside with water and let dry.
