Material Recycle Machine
Irma, Felicia, Delia & Greta
These inventors came up with two solutions in one. The first is a recycle machine that can make new items out of recycled material. It works like a compost for all kinds of materials and then sort the material to use as building blocks for new things. One of the new items the machine makes is an alarm system to protect animals during forest fires. It works by sounding an alarm to to guide animals away from the fires and into safety.
