You must spin and heat  sugar to make cotton candy at home
yes, when i have free time that is all that i ever do
You can make cotton candy at home with a few tools such as a  large pot, thermometer, and a modified whisk
yes, i save money making my own. 
It would be profitable to sell homemade cotton candy. Materials cost about seven cents, and if you sell for a dollar, you could make 93 cents per sale.
That is such a great idea, thanks. I will speak to my husband about it when he gets home.
You could also invest in a cotton candy machine. They come in a variety of sizes from large commercial ones to small tabletop models.
Oh yes, I'll get one for me and my hubby. 
The Flufftastic Cotton Candy Machine is considered an efficient machine that is fast as well.
I hope that I can find one on Amazon. 
Dont forget about looking for important safety features, such as a locking bowl so the hot sugar will not spill.
Yes that would be wise. 
If you want a commercial machine, the electric candy floss can produce 2-3 servings per minute.
