Picture of Creating an Indoor Halloween Atmosphere

You probably do a great job of decorating the outside of your house for Halloween. I know I do, but a problem that I had is that when the trick or treaters rang the doorbell to get candy and the front door was opened, all of the Halloween themeing stopped. This year I fixed this problem and continued the Halloween atmosphere inside when the front door was opened.

In this Instructable, I am going to show you how to continue a really good Halloween atmosphere inside of your house. At the bare minimum, all you need are some white sheets, something to hang them with, an oscillating fan, and a black light, and then you’re ready to go…

Step 1: Hang the sheets...

Hang the sheets. I hung my sheets using a system that was bought at an Ikea. It consists of two anchors that go into the walls, and a metal cable that goes between the two anchors. I strung the sheets along this cable and made sure everything was nice and secure.

Step 2: Set up black light

Set up the black light. The way my house is setup, I have the front door open up to a raised tile area, and then off to the side, there is a lower computer room. It is in this room where I put the black light. This way, the trick or treaters couldn’t actually see the black light bulb itself, but they could see the glow it produced on the white sheets. I always feel it is very bad for your atmosphere when setting up a haunted house to allow trick or treaters to see black lights. They hurt your eyes. The ultraviolet light is actually eating away layers of anything that glows. That’s why black lights making things glow, and if you notice, the whites of your eyes glow in black light. I don’t like looking at them for this reason, and besides it is better to have the glow coming mysteriously from some unknown source rather than from a seen light fixture.

"The ultraviolet light is actually eating away layers of anything that glows." ... um, no. The reason certain objects fluoresce under UV is because the substance absorbs the UV radiation, and this absorbed energy causes it to emit light, but this time in a visible part of the spectrum. There is certainly no "eating away"! With regards to your concern over black-lights being dangerous, they are actually harmless. Black-lights do not actually emit true UV radiation, if this was the case you would not see the purplish glow from the light itself as UV is not detectable with human eyes. They actually emit near-UV radiation, which is near enough to the UV end of the spectrum to enable UV fluorescence, but not at a high enough frequency to damage the eyes or cause other problems associated with true UV. Good Instructable though!

Make sure before you hang the sheets you give them a run through the washing machine...Laundry soaps contain "bluing" which is added to make your clothes look brighter. Without being washed, it may not glow. Found this out when i made a ghost out of cheesecloth without washing it first. Had to put tide in a spray bottle. Porch was very slippery lol
You can buy just bluing in a bottle in the laundry section of stores. Perhaps a douse in that would make things extra glowy? I never knew that bluing caused glowing in black lights, thanks!
Yes that would work quite well. I was unaware that they sold it separately. Unaware of the cost of it, but it is very expensive the laundry soap does its job. Although i'm sure that "true bluing' would probably give awesome results! Either way people....just make sure that u do one or the other. Other wise...very possible...no glow @ all!
It's about 4 dollars per 8oz bottle online, and I think I've seen it cheaper at the grocery store. You can also grow salt crystals with it!
i'm going to use this sheet-blacklight method to cover up a baby gate at my halloween party. (the baby gate is to stop my puppies from going in the front room) great instructable!
I like it verry well set up
