Make a volcano.
You will need to make hill with a cup like hole in it(just put a small glass or stainless steel bowl (Pialy) with baking soda in it, attach a tube to the a funnel and bring a mixture of water and vinegar in the cup. you can hide the tube and the funnel and have a valve that you can open from time to time.
You will have two hills one to hide the funnel with water and vinegar, second to show volcanic crater, funnel should be higher so mixture will flow.
You can get earth, from people who make Murty during Ganesha Pujaa to make the model on a plywood.
