Mr Fixit Rick has been hard at work building a machine that demons from the afterlife can talk through. It makes for a great Halloween centerpiece. Well maybe it doesn’t exactly channel demons but it is still lots of fun. If you want to have lots of spooky fun you can even build your own! There is still time to enter your Halloween Project into the Contest.
