  • Hot melting glue
  • Cutter
  • Bamboo sticks 
  • Scissors
  • Drill machine

Materials required

  • Two 20 ml syringes
  • Two wooden sticks
  • Another wooden stick that is comparatively longer than the other sticks
  • Nut bolt
  • Plywood base
  • Tube
  • Tube connector

And finally, you are ready with your Hydraulic Crane for your science project.


  • It is harder to pin the holes in the wooden stick through nails and hammer, so use a drill machine instead.
  • Take help from your elders if you’re below 18.
  • Make sure you’re using syringes that are not in use.

Points to remember

Handle the tools safely.
