While this project is from a few years back, we think it’s a timeless Halloween go-to build and tutorial. From instructables user marc92!
Fog machines are common equipment when it comes to Halloween, but they have their drawbacks. They shoot fog in only one stream, and the fog is limited to the color white. Now you will be armed with knowledge about how to create a fog spreader that has colors which you can change with the flip of a switch.
