“This is a Hydraulic Gate Working Model made using syringes and cardboard.It demonstrates Pascal’s Law – the principle behind hydraulic systems. When I push the first syringe, water pressure moves the second syringe’s plunger, lifting the gate.Such hydraulic gates are used in dams, canals, and flood control systems. Materials Required: Video Steps to Make the … Read more
This is a hydraulic lift working model in a scissor shape, made using syringes and ice cream sticks/cardboard. It demonstrates Pascal’s Law, where pressure applied on a fluid in a closed container is transmitted equally.When we press one syringe, the water moves into the other, pushing it out and lifting the scissor mechanism. This model … Read more
This is a working model of the human respiratory system.The plastic bottle represents the chest cavity.The two balloons inside are our lungs, and the straws act as the trachea and bronchi.The balloon at the bottom represents the diaphragm, which plays a key role in breathing. When we pull the bottom balloon (diaphragm) downward using the … Read more
This is my working model on Rainwater Harvesting and Water Purification. When it rains, water falls on the rooftop of the house. This water is collected through pipes and directed into a storage tank. The collected rainwater may contain dirt and impurities, so it is sent through a 5-step filtration system: After this process, the … Read more
This is working model on Photosynthesis, the process by which green plants make their own food using sunlight, water, and carbon dioxide. As you can see, the LED light represents sunlight, which helps the leaves carry out photosynthesis. Water is absorbed from the soil through the roots, and carbon dioxide from the air enters the … Read more

An automatic barrier gate operates using a DC motor and a rotating arm, controlled manually or with sensors. It’s used to restrict or allow vehicle access in areas like parking zones or railway crossings. This model shows how an automatic barrier gate works using a DC motor to control the movement of the gate arm. … Read more
This model demonstrates how hydraulic pressure can lift heavy objects using syringes filled with water—mimicking how real cranes operate in construction and industries. This hydraulic crane works on Pascal’s Law, which states that pressure applied to a fluid is transmitted equally in all directions. The syringes use water to transfer pressure, which moves the crane’s … Read more
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 … Read more
This model uses hydraulic pressure to compress a balloon or soft object between two platforms, showing how force applied to a small area can be transferred and multiplied using liquid-filled syringes. This is a Hydraulic Press model. It works on Pascal’s Law, which states that pressure applied to a fluid is transmitted equally in all … Read more
