Friday video: Excavator model with syringe hydraulics

What would you do with a wooden fruit crate, some PVC piping and a few syringes? Make a working hydraulic excavator model, of course.

Wesley Pereira de Souza, from the central Brazilian state of Tocantins, has shown great model-making and engineering ability in making this excavator arm from recycled materials, beautifully carving the wooden  structure and ensuring the smooth operation of the moving parts.

He’s pretty adept as an operator as well.

This video was shot in 2013, when Wesley was 15 years old.
