How do you lift a hovercraft off the table?
Let go of the balloon and give the hovercraft a gentle push. air flows out of the balloon, through the spool, and under the CD. Because the CD has a very flat surface and is evenly weighted, it lifts the entire hovercraft off the table.
How do you use a hovercraft?
Set the hovercraft on a hard, smooth table and open the pop-top; then nudge the device along and see what happens. A hovercraft works by forcing air out beneath it, creating a cushion of air to float on.
What makes the hovercraft slide in the table?
Learn how air and friction makes the hovercraft to slide in the table. Hovercrafts might be old-fashioned means of transport, but they offer a ton of fun and education to children as a science fair project. Today, we will learn about creating a ‘homemade version of hovercraft’ using just an old CD and a balloon.
How does balloon hover craft work?
The small hole in the centre of the CD forces air escaping from the balloon downwards. This creates an opposite force upwards which lifts the hovercraft off the ground, explained by Newton's Third Law of Motion. The CD spreads out this force evenly along the bottom of the hovercraft.

How does a homemade hovercraft work?
How does it work? The air flow created by the balloon causes a cushion of moving air between the disc and the surface. This lifts the CD and reduces the friction which allows the disc to hover freely. Large scale hovercraft are capable of traveling over land, snow and water.
How do you make a balloon and paper plate hovercraft?
Pinch the end of the balloon to hold the air inside. Flip the plate upside down and place on a flat surface. Release the balloon. The air pressure from the balloon will cause an air pocket to form under the plate, allowing it to rise just slightly and move across the plate until the balloon runs out of air.

How do hovercrafts move forward?
Hovercraft use blowers to produce a large volume of air below the hull, or air cushion, that is slightly above atmospheric pressure. The pressure difference between the higher pressure air below the hull and lower pressure ambient air above it produces lift, which causes the hull to float above the running surface.
How high can a hovercraft fly?
How high above the ground can these vehicles hover? This can range from six inches to over seven feet. It depends on the size of the hovercraft and the power of its engines. To help hovercraft engines work most efficiently, hovercrafts have skirts made of fabric surrounding their bases.
Do hovercrafts fly?
WHAT IS A HOVERCRAFT? A light hovercraft flies up to 9" off the surface on a cushion of air. It will fly over any relatively smooth surface - water, grass, ice, snow, mudflats, or marshes - and can be used year-round for sports, recreation, commercial or rescue purposes.

How to put balloons on CD?
Place the inflated balloon over the Bottle cap on the CD by stretching its mouth region around the cap. Take assistance from somebody to help you out while fixing the inflated balloon to the cap. Adjust the balloon’s position and make sure it is straight and positioned at the middle point of the setup. That’s it!
How to make a water bottle for a CD?
Step-1: In the first step, carefully cut the neck part of the bottle and separate it out. Step-2: Now, seal the cut piece of the water bottle at the center of the CD using hot glue or blue-tac. Wait for some time until the glue gets dry, so that the bottle piece is attached to the CD perfectly.

How does a hovercraft work?from learning-center.homesciencetools.com
A hovercraft works by forcing air out beneath it , creating a cushion of air to float on. Hovercrafts usually have a “skirt” that surrounds the base to contain the air; in this project the CD is light enough that it doesn’t need a large cushion, so no skirt is necessary. The balloon acts as a pressurized gas chamber.

How does the sidewall of a balloon work?
The sidewall of the balloon closes this air entry opening preventing the balloon from deflating until you blow on the tube and the air pressure in the tube overcomes the air pressure in the balloon and the wall of the balloon lifts to let the air into the balloon. [While you inflate, put your finger over the small bottom hole that lets air escape under the disk.]
