In this Instructable, I’ll show you how to make a cheap motion detecting confetti popper using a mousetrap and an air freshener.
Confetti Party Poppers – these are almost always available around New Years or the 4th of July. But if you can’t find them, you can order them here: http://www.amazon.com/OTC-Champagne-Poppers-Dozen/dp/B0008F6O84/
Mouse Trap – Available at most grocery/hardware stores.
Glade Sense And Spray Air Freshener – Available at most grocery stores .You can also buy it here: http://www.amazon.com/Glade-Sense-Spray-Motion-Sensor-Clean/dp/B001V53R4E/
L-Bracket – You can find these at most hardware stores also.
Various Hardware Tools – Drill, Nuts, Bolts, Screwdriver, whatever you deem necessary to make this build easier.
The key to making this project work is the Glade Sense And Spray Air Freshener. It has a motion detector that triggers a plastic arm to move up and down. Basically we will be using this to trigger the mouse trap and pull the string of the party popper.
Read the warnings on the party poppers, as they should not be pointed at the face. Also, you’ll be working with a mouse trap, so expect to catch your fingers at least once.
Step 1: Modding the Air Freshner
Step 2: Attaching the L-Bracket
Attach the air freshener to one of the middle screw holes on the L-bracket facing outwards. You can do this with whatever you have available, be it hot glue, screws, bolts, super glue, etc. On the inside of the L-bracket, attach the mouse trap. You want it oriented so that the L-bracket is facing forward and the mouse trap is setting flat on the table.
