i need to make a 3D model of an organ in the digestive system besides the esophagus. I cant use play-doh or styrofoam. What other things can I use?
I suggest you study a good diagram of the digestive system. What do the intestines or stomach or liver remind you of? For instance, the stomach reminds me of a partly inflated balloon and the intestines remind me of snakes or worms.
Then go to a craft or hardware store and wander around until you see something that resembles part of the digestive system.
Also remember that digestion begins in the mouth. So you could focus on this as well.
