Halloween: Dry Ice Fog Machine

Step 6: Wire it Up!

The wiring is super simple, just connect the positive end of the LED to the positive wire on the battery clip. Then, connect the negative end of the LED to the positive wire of the fan. Last, connect the negative wire of the fan to the negative wire on the battery clip. In case you don't know (you probably do) the black wire is usually negative and the red wire is usually positive.

Your waterless fog machine is complete! Just add dry ice and have fun!
