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 shows how real hydraulic lifts work in garages and industries to raise cars and heavy loads.
Materials Required:
- 6–8 ice cream sticks or cardboard strips (for scissor arms)
- 2 plastic syringes (10ml or 20ml, without needles)
- 1 plastic tube (to connect syringes)
- Fevicol or glue gun
- Cardboard base (platform)
- Bottle cap or small platform (to hold the lifted object)
- Water (to fill syringes)
- Paint and color paper for decoration
Model Making Video Steps:
Step 1: Make the Scissor Lift Arms
- Take 6–8 ice cream sticks.
- Make 3 or 4 pairs in “X” shape by connecting their centers with a paper fastener or glue.
- Join the ends of the “X” arms to form a scissor-style expanding lift.
Step 2: Fix the Base and Platform
- Stick one side of the scissor lift on a cardboard base.
- On the top, attach a bottle cap or cardboard piece to make a platform for lifting.
Step 3: Set Up Hydraulic System
- Take 2 syringes, fill one with water, and connect them using a plastic pipe tightly.
- Stick one syringe to the base, and the other syringe’s plunger to the bottom arm of the lift.
- Pressing one syringe will push fluid to the second syringe, extending the plunger and raising the lift.
Step 4: Decorate
- Paint the arms and base.
- Add labels: Pascal’s Law, Hydraulic Pressure, Scissor Lift, etc.
