CD Hovercraft revisited 20230920
CD Hovercraft revisited 20230920. This time I have a 3D printer, so I printed the adaptor to hold the balloon, but you could still use a bottle top.
In response to several comments on my original 2013 video I have revisited the CD hovercraft a few times and I have answered a few questions too.
I think there is probably an optimal size of balloon. The small one I used did not last long. Larger balloons are too heavy and unbalance easily so I guess it will just be a matter of try it yourself.
I have noticed from other peoples videos that they blow up the balloon first then attach it to the bottle top. This gets over the problem of blowing through the bottom of the CD when it gets dirty after has been on the floor. Seems like a sensible approach to me.
Some people have asked what is the purpose of this experiment so I searched YouTube and found this example by AirFloat "35-ton Load Floats on Air" • 35-ton Load Floats on Air
I found this article whilst surfing the web and thought that people who are interested in this type of hovercraft would be interested http://rippl3d.com/hover-craft-challe...
Karolis Giedratis asked if it worked on water. I have tried it on water and it unbalances and tips over so all the air escapes. Interestingly it still moves forwards but that is because it is being pushed through the water by the air bubbles, not floating on a cushion of air.
Main components
-
CD or DVD
3D printed adaptor or
Plastic drinks bottle resealable top (You can make this with any suitable sized tube but it may be more difficult to fix to the CD and you have to hold the balloon to stop the air releasing before you are ready)
Hot Glue Gun or Superglue or two pack epoxy
Balloon
Main Tools
-
3D printer
You may need a saw to cut the top off the drink bottle if it is different to the one I used.
