physics working models for science exhibitions
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 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 is a Tower Crane Working Model that demonstrates both 360° horizontal rotation using a robo motor, and vertical lifting using a slow DC motor. Such cranes are used in real construction to lift and move heavy materials. This model shows how motors, pulleys, and simple circuits help in lifting and rotating heavy loads efficiently. … Read more
This is a working model to show that salt water conducts electricity. Pure water is a poor conductor, but when salt (NaCl) is added, it dissociates into Na⁺ and Cl⁻ ions, which help carry electric current. This is why the LED/buzzer only works when salt is mixed with water. It demonstrates the concept of electrolytes … Read more
This is a Mini Lift Working Model. It uses a DC robo motor to pull a lift box up using woolen thread. The lift works like real elevators, where motors and pulleys lift the platform. The motor is powered by a 9V battery and controlled using a switch. It demonstrates basic principles of mechanical work, … Read more
