While the kids won’t be able to make wireframe structures such as a tower, they will be able to make bubbly bunnies, kittens and other shapes. The Awamoko 3D Foam Pen is a chunky version of a regular 3D printing pen. In order to turn liquid soap into foam, it has to keep it in an adequate chamber inside, and that is what gives it its chunky size. Another plus difference between regular 3D printing pens and this kiddie device is that you won’t need any special composition for it to work. That means, you’ll need to lock away all your liquid soap in the house so that you don’t end up on empty in no time.
