11. Laser Pointer Grid Pen
Rather than investing in a larger and more expensive version, this pen will be sufficient enough to test your home for movement in smaller areas. To make the best use of this, point it in corners or at a wall in a smaller room. The pens are easier to transport, especially since they can fit in all sorts of places like pockets or bags, and can be set on tables, bookshelves, or somewhere a little more discreet.
There is the chance for false positives, but it’s still a neat little gadget to test out around the house as a substitute for an Xbox Kinect. It also has other uses; it can serve as a ghost hunting tool, a laser pointer for cats, or even to set the mood for a Halloween party.
