Hello. I am demonstrating the comparison of a normal brain and a brain aneurysm. So, I would like to use a model of both types of brains.Does anyone know anything that could make a good model besides clay? I was thinking putting some type of pasta over a circular surface but I don't know. Any suggestions?

To save on space and materials the best course of action may be to make a single brain with 2 lobes and have an aneurysm on one side and a healthy brain on the other. A lighter weight material such as Styrofoam or the green blocks used for planting fake flower bouquets may make an easier medium to work with. If you then want to coat the outside in clay you can use the blunt side of a spoon to make ridges and creases. 

To show the ballooning of the blood vessel that comes with a brain aneurysm try to find a narrow tubing that you can run through the grooves of the brain to represent vessels. Cut a small hole in a part and attach on a small section of balloon material. That way, if you blow through the tubing that makes the blood vessels you could show the ballooning of the vessels in the weakened section while the other side stays healthy looking. To really demonstrate the danger, run a fluid like water through the piping using a water bottle with a small hole in the cap. Squeeze until the ballooning section bursts, demonstrating a brain hemorrhage. I hope I gave you some ideas!
