Question: How come thise machine throws so much sugar onto the sides? Am I doing something wrong?
Document: it works great, though there are couple problems. one  -when it spins it vibrates and the metal drawer comes out constantly so i ended up taping it. two-  after the sugar spins and makes the cotten there is so much left over sugars on the sides... wasting (i think at least half the sugar) either than thiese it works great.
I purchased this machine for my office and it has been a huge hit! We have enjoyed the Great Northern Popcorn machine and felt the need for something sweet to serve as a special treat for employees. We ordered the cotton candy machine- along with the very necessary dome (sold separately) Much to my delight it arrived promptly! After finding a youtube video demonstration on how to make cotton candy, we got to work. The machine works beautifully, and makes delicious, fluffy, cotton candy just like the fair- without all the crowds!
But I'm pretty sure this is normal for a cotton candy machine? I feel like when you watch youtube videos of people making cotton candy, all the machines have hard sugar around the sides & the sugar washes off super easy.-- This machine will totally work for a big birthday party or small fundraiser. It takes maybe a minute to make a cone, if even that.-- I'm sure you already know, but just in case you don't... If you buy the pre-mixed cardboard cartons of cotton candy sugar online or at smart & final, they are convenient, but a little pricey for what you get.
I seriously love this purchase. I will try to remember to review it again a year from now, though...because that's the kicker, isn't it? For $250, we'd like this thing to last at least a couple of years...but no one ever tells you how long their machine lasted, or whether it worked well for the duration. And really, that's something we'd all like to know...so I'll try to do that.A few tips and FYI...-- One scoop (1.5 TBS of sugar) makes a decent size cotton candy cone.
I use this machine for the first time last week since I got it, the candy are fine the only thing is that it waste a lot of sugar and it vibrates a lot on the table and make to much noise wish their was a way that I can fix it from making so much noise.
Mine didn't come with the metal measuring tool that it was supposed to, but I ended up just filling up the center to full, spreading it around and topping off. It produces between 6 & 7 candy cones when fully filled. Also, a quick tip. You can make your own cotton candy cones with plain white 8x11 copy paper. Much, much cheaper. However, sometimes it can slide around on the cone if you don't pinch it at the bottom of the cotton candy to provide a base. But again, much more economical if your kids are just going to eat the candy and throw the cone away.
We used to rent a machine every year for our big summer party (60+ people). I decided it would just be easier and cheaper to buy our own. It has held up very well, and can handle large amounts of people. It is messy, and I will probably buy the shield at some point, but until then I just wear washable clothes and end up looking kind of shimmery from all of the sugar. The machine itself cleans up very easily, much more easily than I anticipated.
I purchased this after searching for quite some time to find one that would fit my needs as I originally purchased the small  household one with much disappointment in the performance. My intentions are to use this for personal use. It was used for the first time today and I can't tell you how excited I am from the results. Read the instructions on how to use the machine and you will not fail. After letting the machine warm up for the recommended amount of time, I poured the scoop full of sugar in and the floss resulted almost immediately.
This model throws a lot of sugar to the side of the bowl instead of allowing it to become cotton candy. The first model we bought we had to return as it threw most of the sugar to the side instead of allowing it to become cotton candy. Amazon was SUPER good about the return and the second unit does work better. Although it arrived with one of the feet of the machine bent (I assume in the shipping process). It will have to be unbent to make the machine stable. You will be able to use this machine to produce cotton candy as a novelty at your kids parties and other gatherings like that; however, dont expect you will be able to use this machine as a way to fund raise.
Like a lot of the other reviews ours was dented on one corner, but the bow was fine. Wierd. We have really had a lot of fun with it. My only complaint is that it wastes so much sugar. I think about half of the sugar I put in gets flung in a ring around the edge and is wasted.
Answer: It is just excess sugar.  I've found that some types sugar/floss does this more than others.  You can snap the sugar ring into small pieces and put it back in the machine and it will make more cotton candy... It doesn't need to go to waste.
