It Will Blow You Away...Air Cannon

I will never forget the first air cannon I experienced while going through a haunted house.  The unexpected sense of terror it left me in.  I look back now and kind of wonder why it took me so long to build one for my own haunt.  But now I have and hopefully it will bring that sudden jolt of panic to those who wander around Blood Moon Cemetery.  The first part of this blog will show a video of the prop in action. It includes the build, the test run, and an actual live test run.  At the end, I will give a "how to" for those wanting to build this.






Ok, so here it is in all its pride and glory.  Of course you have to have some sort of air tank to build this air cannon.  The good news is, you can get them pretty cheap if you are on the look out.  Try garage-sales or ebay and you could possibly pick one up for $5-10.  I will not add any measurements because different tanks could be different sizes, but I basically measured how long and high I would want the steel pipes to be and went from there.  Of course I put teflon tape on all threaded ends so air would not leak out.


A.  NPT Check Valve.  It basically lets air in but not out.  Makes it portable.

B.  NPT Air Pressure Regulator and Gauge.  It helps maintain and regulate air flow.

C.  Electric 12v Solenoid Valve.  When powered, it allows air to pass through.

D.  Galvanized Threaded Steel.  You will need a Tee, Bushing, or anything to properly assemble this build.

E.  Simple Prop Timer. 



This is the simple prop timer that I have had for a while from Fright Props.  While you can choose a different method of powering the solenoid valve, this is a very simple and effective way of doing so and  you can set a timer on how long you want the solenod valve powered.

The settings on this timer are: Trigger, Negative (-), Positive (+), NO (Normally Open), C (Common Lead), NC (Normally Closed)

Fright props has a "how to" on wiring this but all I did was connect the trigger to the Trigger and Positive, Connect the 12v Power Supply to the Negative and Positive, connect the Solenoid Valve to the Negative and the C, and then cut a separate wire and run the ends to the Positive and the NO.

All in all I built this prop for $35 not including the simple prop timer that I already had.  If you find the right prices you could possibly build it cheaper, but for $35 I still think it is the best scare for your buck!  If you have any questions, email me at mr.halloween@bloodmooncemetery.com

My Bloody Valentine

On a day where chocolates, stuffed animals, jewelery, and flowers are the norm, my wife proves to me that she truly knows my bloody heart.  I can honestly say that this is the first time ever I've received a valentine that truly blew me away.  Was I expecting anything like this...no, no, and no.  That is what makes it so great.  So I would like to publicly say I have the best wife in the world that truly knows what I like and is actually ok with it.  So thanks for my valentine, my armless, legless, entrails dragging, brain popping out bloody valentine!


  

Sorry for the poor quality on the pictures.  I could not find the sd disk to the camera, so I used my phone camera and had to get this on here tonight.
