A portable water containing tray that uses various mediums to demonstrate and/or experiment with liquid and gas flow dynamics. It is designed to be compatible with overhead projection and contains a transparent activity area, fluid transport system, and activity components that when placed on an overhead projector allows light transmission through various liquid and/or solid object components. Fluids are recycled on the activity area by a pumping device. Various liquid dye and solid object components are placed on the activity area to simulate real-world events or environments. Solid activity components have a variety of internal and/or external flow configurations for creating a multitude of flow characteristics.
