    No one, not even a very strong human, is strong enough to lift a truck. However, our brains are smart enough to create a tool that can lift heavy objects for us: hydraulic lifts! You find them in body shops, on skyscraper construction sites, in wheelchair lifts, and in dentist chairs, and you will even build one in this activity! Try it out and dis...

    If you have ever used a wheelbarrow, you know it can help you lift heavy objects; lifting the handles of the wheelbarrow is easier than lifting the object itself. A hydraulic lift does the same; it allows you to move a heavy object with very little effort. The term “hydraulics” refers to tools that operate by using moving liquids like water or oil....

    Two stainless steel wall plates, at least 4.5 x 2.75 in size. These are available in any hardware store.
    Two small and one large syringe. The combination of 25 cc and 60 cc syringes works well. Look for syringes with a catheter tip as these tips can easily be connected with a plastic pipe.
    Epoxy glue, paper plate, and disposable spoon or extra-strong wall-mount double-sided tape
    Two feet of silicone fuel tubing, with a 5/32-inch inner diameter. This is available in a hobby shop, a hardware store, or online.

    You were probably able to lift much more weight with the large secondary syringe compared to the small secondary syringe, and the jar probably moved over a much shorter distance. That is exactly what happens in a hydraulic lift when the secondary piston is larger than the primary piston. When you press one piston, the liquid inside the closed syste...
