How To Make A Homemade Fog Machine Cheaply
If you want to make a fog machine for your home display and don't want to spend a lot of money, here are some recipes for fun.
A do-it-yourself Haunted house could be something the trick or treaters will enjoy and make your home the talk of the neighborhood. One thing that will add the perfect effect to the lights and props for this Halloween? How about some creepy fog to set a mysterious mood. Build this DIY fog machine to set a scary mood throughout the night.
Don't bother putting out any money to rent a fog machine. For a lot less money than it takes to do even the old dry ice in a bucket of water routine, you can build your own fog-making rig from a few bottles and chemicals. It won't cost you more than a few bucks, in fact I have a video that you can make it for $5.
Here are some Ingredients from Popular Mechanics:
•One large candle, preferably with multiple wicks
•A small aluminum pie plate
•The top of a 2-liter plastic soda bottle
•A gallon of distilled water
•A small bottle of glycerin. Glycerin can be found at your local pharmacy or at a site such as Amazon.com.
How to Make a Fog Machine from Popular Mechanics:
Make your "fog juice" by mixing a solution of one part glycerin to three parts distilled water. The "fog" is created when the solution is heated to the point of evaporation. The process leaves an accumulation of dense vapor, which becomes cloudy when it hits the room-temperature air.
Make your haunted-house fog machine by cutting the top off a 2-liter soda bottle and taping the narrow end onto the small aluminum pie plate, creating a basic cone shape.
Position your fog machine over the lit candle. This can be done by taking an empty metal coffee or large soup can—without the lid, of course—and poking out several vent holes around the base of the can's sealed end, perhaps with the pointed end of an old-fashioned metallic can opener. Next, drop the candle into the can, light it, and place the pie tin/fog machine over the can's open top.
Add a teaspoon or so of fog juice. That should produce enough fog to fill a good-sized room.
To replenish the fog, just pour additional teaspoons of fog juice into the fog machine as needed. Let the spookiness ensue.
