From Revision3:

In honor of last year's Halloween Project, the Motion Activated Silly String Shooter, we bring you two more projects for the spookiest night of the year!

First, we'll add a adding a special touch of strange to any indoor or outdoor décor when we build A Brain In A Jar. It's fun, easy to build and safe enough to build that your kids will have a blast helping you put it together. Best of all, the parts are easily and cheaply purchased or re-purposed items you probably have in your kitchen or garage. If you spend big money on the brain you might spend $50. Sure, you could build a similar product that's sold as a kit. (If you don't mind spending a lot more money.) We say do some scrounging and go DIY: it's a lot more fun!
