This working model is a Water Fountain, demonstrating how a closed water system uses a pump to circulate water. It also helps explain concepts of pressure, water recycling, and motor-powered flow systems. Such mechanisms are used in gardens, buildings, and artificial water features.
This model demonstrates a recycling water fountain using a DC water pump motor, simulating the water cycle and principles of water flow, pressure, and reuse.
Materials Required:
- Plastic or thermocol ball (large, hollow or decorative)
- DC submersible water pump motor (3V–12V)
- Plastic tray or tub (to hold water)
- Transparent pipe or straw (to carry water upwards)
- 9V battery or power source + switch
- Cardboard (for support stand)
- Glue gun or tape
- Decorative items (stones, artificial plants, lights – optional)
Video Step-by-Step Instructions:
1. Prepare the Base Tray:
- Use a plastic tray to hold the water. This acts as the reservoir for the fountain.
2. Install the DC Pump:
- Place the DC water pump inside the tray and connect a flexible pipe to the outlet nozzle.
- Secure the pump so it stays at the bottom and underwater.
3. Create the Ball Fountain Top:
- Take the plastic or thermocol ball and make a small hole at the top and bottom.
- Pass the pipe through the ball vertically—secure it inside.
- Water will travel up the pipe and spray out from the top hole.
4. Build the Support Structure:
- Use cardboard or a stand to hold the ball above the tray, allowing water to fall back down like a fountain.
- Ensure all wiring is above water level and safe.
5. Connect the Circuit:
- Wire the DC motor to a 9V battery and a switch.
- When the switch is ON, water is pumped up and flows out from the top of the ball, falls back into the tray, and recirculates.
