What exactly you need:
Blank CD or CD that you do not want any additional.
Pop-top cap coming from a water bottle as well as dish soap package
Balloon
Hot glue rifle
What You Accomplish:
Use the scorching glue gun for you to carefully glue your bottle cap in the center hole in the CD and allow it to go set. Make confident the edges are generally fully sealed.
Force the pop-top hat closed. Blow up the balloon, then hold it to ensure no air escapes, but don't tie up it off. Stretch the mouth in the balloon over your bottle cap (you might require an assistant that may help you do this so that you can don't lose any air through the balloon). Now adjust the balloon in order that it stands up direct and centered.
Set the hovercraft with a hard, smooth kitchen table and open your pop-top; then nudge the product along and see how are you affected.
What Happened:
A hovercraft operates by forcing air out and about beneath it, setting up a cushion of air flow to float in. Hovercrafts usually have a very "skirt" that surrounds the camp to contain air; in this undertaking the CD can be light enough who's doesn't need a huge cushion, so no skirt is critical. The balloon acts as being a pressurized gas slot provided. When you wide open the cap, the balloon allows air out over the cap, creating a skinny cushion of air within the CD.
As anyone nudged your hovercraft all-around, you may have remarked that it zipped down the surface like the air hockey puck. That's because air flow hockey uses a similar principle, with the puck floating with a layer of air flow. In the case associated with an air hockey kitchen table, the air is forced out of your table below rather than source above as being a hovercraft. Try pushing an ordinary CD across your table, and after that your hovercraft. Do both the move differently? That's for the reason that thin cushion of air through the hovercraft reduces the friction relating to the CD and your table. Because in the reduced friction, hovercrafts could reach higher data transfer rates.
Experiment ideas:
Test to see should your hovercraft works differently in case you open the hat only part way instead of all the so-called way.
Try distinct sizes of balloons. Does the hovercraft run longer with a larger balloon?
Hovercrafts work ideal on smooth surfaces hence the air can propagate evenly, but research yours on several unique surfaces to see how it behaves. Should it work on a new sidewalk or rug?
