Make brings up this handy resource to add a little fright to your front yard this Halloween. The Haunt Project is a collection of Halloween-related DIY projects, ranging from harmless decorations to stuff that's just dangerous.
The picture above is a crashed UFO prop, complete with chasing LED lights.
Or there are the "ghost sliders," where you attach a set of casters to kneepads in order to drift across pavement like a ghost. This is dangerous. Don't blame me when you end up eating asphalt instead of candy and get your jaw wired shut.
There are hundreds of projects at the link. Check it out if you need something to keep you occupied this weekend. [Make]
