This video shows how to use some pneumatic equipment to make a Halloween witch that jumps out of a bin once the passive infrared sensor is activated. To make this project you will need a suitable compressor, a pneumatic cylinder or rod less cylinder, a 12 volt, five port three way pneumatic solenoid valve, a 12v Passive infrared sensor, some wire and a 12v battery. You will also need a zombie or a witch to pop out of the bin. The witch in this video was purchased from B&M bargains.
Once this equipment is set up you are guaranteed hours of fun with the kids, or just scare the neighbours.
Special thanks go out to my neighbours Ian and Carole who were really good sports in this video ;-)
