For this assignment, I wanted to make a simple toy, in a shape of an egg. So when you hold it, your hand  will warm it up and a little embryo in the egg will feel the warmth.

The real challenge was perhaps, making a mold of an egg without breaking it...

So instead, I decided to make a clay egg first, and then make a mold out of it.

Used a string to slice the clay egg into two hemispheres so it wouldn't stuck in the mold.

Mold made successful! Chose a very opaque polymer, which I regret a lot.

Three temperature sensors and three LEDs were attached to the casted polymer.

Done, thanks to the glue gun, my favorite tool all the time.

This is the final product in action!
