DIY Cotton Candy Machine

by David Weinberg |

The specialized hardware required to make cotton candy usually limits it to a carnival food. At its simplest, a cotton candy machine is basically just a spinning heated container filled with sugar. As the sugar melts, it liquefies and slips through holes in the container. The sugar cools as it comes out of the holes and turns into long threads.The threads then stick onto the outside of a bowl that is placed around the outside of the container.

Below you will find instructions on how to make your DIY cotton candy machine!


1. Drill small holes outside the tin can in columns of three. The columns should wrap all the way around the can with each set of holes being about 1/8 inch away from the next hole. The holes should be about as thick as a pin.

2. Press the bottom of the can against the blade on the blender so that the blender blade perforates the bottom of the can. Center the blade in the middle of the base of the can. Glue the can in place against the blender’s blade. Allow the glue to fully dry according to the instructions on the bottle.

3. Position the lighter or hair dryer so that the heat source heats the center of the tin can. Ensure that the rotating blender will not hit the heat source.

4. Surround the entire machine with cardboard. Tape the pieces of cardboard together to make a bowl around the assembly. The cotton candy will collect on this cardboard when you run the machine.

5. Add a thin layer of sugar to the bottom of the can, turn on the heat source and turn the blender on its slowest speed setting. Collect the wisps of cotton candy off the cardboard with the wooden dowel.

Tips & warnings:

  • Use caution with your heat source.
