The Prosthetic Leg
A prosthetic leg could be used for somebody who unfortunately has lost a limb. They are basicly are hard plastic items that come in all different shapes and sizes. The one I want to make is for walking or jumping in space. The material that it will be made of is a hard plastic and metal. The function of this leg is in case someone loses their leg, maybe working in space and they need immediate surgery, they can go back to earth they have to do the surgery there. That is why a prosthetic leg would be useful. Also some of the medical tools that are already up their can help.
