If you’ve ever wondered what’s inside the McDonald’s Avatar Toy, you might want to see that there’s a lot of small goodies like blue LEDs and plus, your kids might drain the batteries. This could be a great way to replace the battery.
The solid clear plastic piece is made of acrylic. It is shaped to distribute the blue LED light more evenly. This is called a “light pipe”, which is used to provide designer-styling in a wide range of electrical devices. This is a really nice touch, but almost seems unnecessary in a plastic container that I would have expected to have fairly good light diffusion by itself.
