This is a hydraulic crane made with syringes and cardboard. When I press this syringe, it pushes water into the second syringe, lifting the arm. This works on Pascal’s Law, which tells us that pressure in fluids moves equally in all directions. Real cranes use the same principle to lift heavy materials at construction sites. … Read more
This model represents the paper output system of a printer. Real printers use motors to push printed paper out. Here, we’re using a simple hydraulic mechanism. When we press this syringe, the connected syringe inside pushes the printed paper forward. It’s a basic example of how hydraulics can be used in machines to move things … Read more
This is a hydraulic bridge working model. It uses Pascal’s Law of pressure in fluids. When I push the syringes, water transfers pressure to lift the bridge arms just like a real drawbridge opens for ships to pass. It’s an eco-friendly, simple, and efficient technology used in many real-world machines. How to Build the Hydraulic … Read more

Farmers face heavy losses when: Traditional scarecrows or fencing are ineffective, and electric fencing is expensive and dangerous. This model solves a common issue faced by farmers – crop damage from wild animals or theft. When any object passes through the field boundary, this sensor detects the movement and triggers an alarm. It can be … Read more
Introduction The kidney is one of the most important organs in the human body. Every person has two kidneys, located on either side of the backbone just below the ribs. They are small and bean-shaped but play a very big role in keeping us healthy. The main function of the kidneys is to clean the … Read more
Introduction A water dam is a large wall or barrier built across a river to stop and store water. The water collected behind the dam forms a big lake called a reservoir. This stored water is very useful for people, farms, and industries. Dams provide water for drinking, farming (irrigation), and factories. They also help … Read more
An escalator is a moving staircase that carries people up and down between different floors of a building. It is powered by an electric motor and works with a chain of steps that keep moving in a continuous loop. Escalators are very useful in places where many people need to move quickly, such as shopping … Read more
Introduction Air pollution has become one of the most serious problems of our time. With the increase in vehicles, industries, and burning of fuels like coal and petrol, the air we breathe is becoming more and more dirty. Polluted air contains harmful gases such as carbon monoxide, sulfur dioxide, and nitrogen oxides, along with tiny … Read more
Introduction A water overflow alarm is an electronic device designed to prevent the wastage of water. It alerts people when a water tank becomes full, usually by producing a loud sound or turning on a light. This simple system helps in saving water, electricity, and avoids unnecessary mess caused by overflow. The device works using … Read more
Introduction Water is one of the most important resources for life, but fresh water is limited and many areas face shortages. To solve this problem, two important methods are used: rainwater harvesting and water purification. Rainwater harvesting means collecting rainwater and storing it for future use. The water is usually collected from rooftops or open … Read more
This 3D model demonstrates both Solar and Lunar Eclipses.The Sun, Earth, and Moon are represented by these three colored balls.In a Solar Eclipse, the Moon blocks the Sun’s light and casts a shadow on Earth.In a Lunar Eclipse, the Earth comes between the Sun and Moon, casting a shadow on the Moon.This model helps us … Read more
This is a 3D atom model showing its internal structure.The center or nucleus contains protons and neutrons, while electrons revolve around it in orbits. Each component is represented with colored balls and glowing LEDs, controlled using switches.This model demonstrates how atoms are structured and the role of subatomic particles. Video Construction Steps: Step 1: Prepare … Read more
Geothermal energy uses heat from deep inside the Earth. In some places, hot water and steam come from underground. This steam can run turbines to make electricity. It is clean, renewable, and available all year. Countries like Iceland and the USA use geothermal power a lot. It can also be used to heat houses and … Read more
Hydropower is energy made from flowing water. When water flows down from a dam, it pushes turbines that create electricity. This energy is renewable, as water keeps flowing in rivers. Hydropower gives steady power day and night, unlike solar or wind which depend on weather. It also helps with irrigation and flood control. But building … Read more
