Air & Water (Wind Turbine Power & Pneumatic Lift Lab)

Source:

Blow air onto a DIY mini wind turbine to generate electricity that lights an LED city, and use water-filled syringes to operate a hydraulic pneumatic crane arm.

Categorisation

Props & Materials Required

  • •Mini 3-blade wind turbine generator (DC motor generator)
  • •LED bulb array (city lighting model)
  • •2x 20ml plastic syringes connected by vinyl tubing
  • •Cardboard crane arm mechanism
  • •Analog voltage meter display / LED barometer

Step-by-Step Instructions

1

Blow on Wind Turbine

Use a fan or blow hard onto the wind turbine blades.

2

Watch City Lights Glow

As the turbine spins, generated electricity powers the LED city lights! Voltmeter shows generated voltage.

3

Pneumatic Syringe Lift

Push the water-filled master syringe plunger. Water pressure travels through the tube, extending the slave syringe to lift a heavy load!

4

Air vs. Water Compression Test

Compare pushing a syringe filled with AIR (spongy/compressible) vs. WATER (solid/incompressible).

Why It Works & Notes

Air exerts pressure and wind carries kinetic energy. Generating real electricity by blowing on a turbine and lifting objects using water pressure in connected syringes makes fluid power tangible.
