One Halloween, my family used dry ice for fog by dumping boiling water on it. I thought "I have an old PC fan... I wonder if I could use it for a fog machine that doesn't use water!" so I built it. I haven't been able to test it yet, so if anyone builds it, please comment how it turns out!
P.S. This is my first Instructable. Please comment!
