Well, First what you do is Cut out a piece of square cardboard for the base and then you scrunch up newspaper and make the shapes of the stadium you want to make then you stick this on the cardboard with PVA glue, Then leave it to dry for about 5 hours then you cover everything in PVA glue and leave to dry all night. After that you can use paints or felt tip pens to decorate your stadium!

No. High impact polystyrene is a very hard plastic. If you tried doing a lost-foam casting you'd just make a mess.You make a lost-foam casting by creating a styrofoam model of your finished piece, packing casting sand around it to create a mold, then pouring metal into the mold. When the hot metal touches the foam, it vaporizes.You could make your model out of high impact polystyrene then use that to create a cope and drag mold.
