Glow Sticks
One of the great and cheap effects for your haunt is glow sticks. They come in many different colors and you can put them pretty much anywhere. Try putting them in.. light up items like pumpkins or other plastic store bought light up things especially if you can’t plug them in, this will light them up about the same, try 2 glow sticks if one isn’t bright enough. Also put them behind things like.. pumpkins and tombstones. Or try hanging some from a tree with some Halloween garland or spider webs. I have discovered that GREEN is always the brightest color when it comes to glow sticks!!
