The original

What better secret than to hide an egg inside an egg? I'm going to nickname this task "hardboiled."

Encased in plasticine

The first step is to divide the egg in two so I can cast a rubber mold.

Assembling the frame

I build a frame of foam core around the plasticine.

Ready to pour

I made sure the plasticine didn't leave any gaps.

Mixing the mold material

Blue and pink make purple!

Letting the mold set

With time, hopefully the air bubbles all rise to the surface. I've never done this before. It's a learning experience.

Removing the frame

So far, so good.

Half a rubber mold

I couldn't have asked for a better half mold. Now time to pour the second half.

Mixing the second half

Blue and pink make purple! I didn't have specific mold release, but I brushed a thin layer of Vaseline on everything so the two halves separate.

The completed mold

Crap. The mold didn't release. Guess I should have bought the real stuff. Luckily I was able to cut the mold open pretty easily and not ruin it, but I did lose the keys I cut into the first half. I'll just have to eyeball it to make sure it's even when I pour the resin.

Setting the yolk

I made the yolk out of polymer clay. I let a little pool of resin semi-set so I can rest the yolk halfway in it.

Pouring the resin

I cut air vents and a pouring plug, and filled it up with clear resin until the resin flowed up the air vents.

The rough egg

Hmm, pretty rough. Did I mention I've never done this before? Lots of air bubbles.

Flash lines

Not too bad, though. It'll just take a little cleaning up.

Polished

As polished as it's going to get.

Preparing the secret

As gentle as I was, I cracked the shell a little bit. It will still serve my purpose.

Halfway there

The secret egg inside the original egg.

Hidden

It's a good thing I had to sand and polish the resin cast, or else it wouldn't have fit inside the original egg. Silly physics.

In the supermarket

It was a dreary morning, the rain making the streets glisten like the sweat on an exotic dancer's forehead. The perfect setting for my hardboiled excursion.

One egg among many

The only thing that will give this away is that there's a spare egg which I left tucked to the side of the display. I didn't want to steal.
