How to Make Disc Hovercraft

A hovercraft is also called ACV (Air Cushion Vehicle). It uses blower to create air current beneath itself to create air cushion that slightly lift it up and reduce the friction with surface so it can move freely to any direction in which it is pushed.
We will Build a model of hovercraft that uses same principle out of home materials.

Required Materials

 

 

 

  • Balloon
  • CD or DVD Disc
  • Cap of plastic bottle
  • Glue gun

 

how-to-make

 

 

 

  1. Make a small hole in center of the plastic bottle’s cap with pen knife or drill.
  2. Cover the center hole of the disc with Cap (that you made in step 1) by putting it on top of disc and apply glue to make air tight contact but don’t apply glue on the hole of the cap.
  3. Blow up the balloon and pinch it shut and than fit mouth of balloon over the cap and release it.

Your hovercraft is ready and working. Put it on smooth surface and Push it in any direction it will go there smoothly.

 

explanation

 

 

 

Air from balloon passes through the hole in cap than flows beneath the disc creating air cushion that slightly lift the disc up and reduces friction between surface and disc so it is free to move and can go in any direction where it is pushed.

 

try-this

 

 

 

  • Use large size balloon
  • Make two more holes in the disc and cover each hole with cap than blow three balloons and fit them to caps (This is easy with three people each handling one balloon)
  • Try to land your hovercraft on water and sand
  • Check how much weight (pencil, rubber, paper clips) your hovercraft can lift.
  • Think! What can you do to increase the payload capacity of your hovercraft.
