Sure! You can get a hot-air balloon type machine from Amazon, or see if you can find a cotton candy maker at a party store.  Or check with your local libraries or makerspace for instructions for making it at home.

What is the relationship between cotton candy and a hot-air balloon machine?  I am confused.
user
The basic principle is the same.  The air inside the balloon is heated and the molecules in the air expand, pushing against the fabric of the balloon.  As the molecules return to normal, they push against the fabric and create a gentle pulling force that makes the balloon rise.  Likewise, as the air inside the balloon cools and contracts, it also pulls against the fabric, so the balloon slowly returns to the ground.  There are a lot of different ways you can attach a machine to the ground to create that “pull” and “push” effect.

I saw this machine on Amazon:  https://www.amazon.com/6315-Great-Northern-Flufftastic-Maker/dp/B012HD3SZQ/ref=sr_1_3?adgrpid=1339205732657688&hvadid=83700572868089&hvbmt=bb&hvdev=c&hvlocphy=73326&hvnetw=o&hvqmt=b&hvtargid=kwd-83700714455885%3Aloc-190&hydadcr=20186_13293919&keywords=cotton+candy+machine+great+northern&qid=1636841245&sr=8-3

Ahem.  The current model uses a hot air balloon.  I don’t think the balloon was that popular on the news or in literature...  but maybe they also sell a helium version?

In my opinion, your responses were slightly irrelevant.
