Hello everyone!!! How have you been?
Greetings to you! Today, 
Okay, air pressure is something I recently tutored my student about too in her Physics. I remember her exam paper had a question of explaining how a hovercraft operates. It's something very foreign to her as she doesn't know what a hovercraft is. My son knew it from Paw Patrol, as Zuma's vehicle is a hovercraft. I found this super easy to make experiment, so I thought I want to try with him at home first and perhaps bring what we have built to my student asked I explain to her the next time.
Just a little reference from www.sciencebuddies.org:
A hovercraft is a vehicle that glides over a smooth surface by hovering upon an air cushion. Because of this, a hovercraft is also called an Air-Cushion Vehicle, or ACV. How is the air cushion made? The hovercraft creates vents or currents of slow-moving, low-pressure air that are pushed downward against the surface below the hovercraft. Modern ACVs often have propellers on top that create the air currents. These currents are pushed beneath the vehicle with the use of fans. Surrounding the base of the ACV is a flexible skirt, also called the curtain, which traps the air currents, keeping them underneath the hovercraft. These trapped air currents can create an air cushion on any smooth surface, land or water! Source
This works based on the principle of air pressure, aerodynamics and also friction reduce to ensure a smooth gliding. It is educational and not too difficult to achieve.
When I was younger, I actually wish I can do more of such things at home but I wasn't that resourceful then. Having watched some of the videos online now and how possible to actually recreate them, I am getting more enthusiastic of sharing simple experiments like this. Let me know if you would like to see more. Hope you enjoyed this video.
Always appreciate your time for watching even though I am not a pro in this yet. I am thankful to 
and 
for making all this possible that even one small tiny person like me can actually relive some of my passion and kicking start again. I promise to improve better in filming and editing as well. Got a new Boya lapel mic too, hopefully the sound is better now. Do you prefer a song in the background to go with it?
