Mirror is a good tools for child to understanding "self-concept".
However, I want a mirror which is colorful, light, safe to use (unbreakable), difficult for biting, and can hold it tight with small hand.
As a result, I make this Acrylic mirror.
Step 1: Prepare the acrylic mirror
I got a spray-paint cap from plastic model spray-paint.
Also, I got a piece of acrylic mirror and use saw ring to cut a circular mirror (which diameter is similar to spray paint).
