A hovercraft operates on the simple principles of air cushioning. This means that high pressure air is trapped under a curtain or skirt in order to suspend the craft above the ground. The high pressure air creates a cushion on which the vehicle rests.
A commercially usable hovercraft is very difficult to build. However, the following instructions can be used to create a model that uses the same principles of a hovercraft to stay suspended on top of high pressure air.
Materials Required to Build a Hovercraft
- Plastic lunch box (preferably Tupperware if you can convince your mum to let you use it)
- 2 or 2.5 inch diameter PVC pipe at least 4 inches long (if not a piece of chart paper can be used to make a tube of proper size)
- Electric hair drier
- Duct tape
- Cardboard
- Paint
- Scissors/ Knife
Steps Involved in building a hovercraft
- Take off the lid from the lunchbox, turn it upside down and use the scissors to make a hole that is around the same size as the pipe section or paper tube.
- Insert the pipe into the hole that has been made on the lunch box and use duct tape to hold it down so that at least 3/4th of the pipe is sticking out of the underside of the lunchbox.
- Use the cardboard and paint to make a body for your hovercraft. But take care not to make it too heavy or the hovercraft won’t be able to lift itself up.
- Once all this is in place, place the hovercraft on top of a flat surface. Point the hair drier into the pipe and turn it on. Your hovercraft will begin to hover.
