Can you make a homemade hovercraft that actually hovers? Learn about how the hovercraft works and build your own mini hovercraft at home or in the classroom from simple supplies. Play with engineering and science with this easy science project idea! We love fun and easy STEM projects for kids!

HOW TO BUILD A HOMEMADE HOVERCRAFT

HOW DOES A HOVERCRAFT WORK?

A hovercraft is also known as an air cushion vehicle or AVC because it can glide over a smooth surface by hovering on an air cushion. Hovercraft can travel over land, water, mud, ice and other surfaces.

Hovercraft use blowers to produce a large volume of air below the hull, or air cushion. The difference between the higher pressure air below the hull and the lower pressure of the air above it produces lift. That is what causes the hull to float above the surface.

Find out how to build a mini hovercraft below with our free printable project. Here you will use a balloon to increase the volume of air below the a CD hovercraft and lift it.

BUILD A HOVERCRAFT

SUPPLIES:

  • Balloon
  • CD or DVD
  • Pop up top
  • Hot glue

INSTRUCTIONS

STEP 1: Hot glue a pop up top to the center of a CD or DVD. Push the top down to close.

STEP 2: Blow up the balloon and twist it closed.

STEP 3: Carefully keeping the balloon twisted, stretch the end over the pop-top.

STEP 4: Now pop open the top and watch your hovercraft travel! Use a smooth surface like a floor or countertop.

TIP: Cover the center hole of the CD with a piece of tape and poke
a few holes in the tape with a push-pin or small nail. This will slow
down the flow of air and allow your hovercraft to hover longer.
