I wanted to make a really sick and disturbing jack-o-lantern. I saw on the internet that someone made a drowning one by putting a jack-o-lantern in a bag and filling it with water. That was pretty cool but not disconcerting enough for me. I had to make something people on the street were going to talk about for a while.
I was inspired by the drowning jack-o-lantern to make a suffocating jack-o-lantern, one that would really try to breath and suck the bag into its mouth. Now that is gruesome! I had to build quite a machine to pull it off and make it "breathe".
Unfortunately I took mostly video and it was pretty dark. I will give you the full video at the end and screenshots throughout. If they look grainy and dark, just think of it as spooky!
Please check out my other instructables and I also have a diy podcast called mechanicalmashup.tv
Step 1: Materials
2 Large clear bags (they don't both have to be clear but since they don't normally sell bags in "ones", you will probably have two clear bags with a few left over)
1 long vacuum hose found in neighbors garbage. + a little duct tape to plug a few holes.
1 large bucket (free from an ice cream store)
1 electric drill (cordless won't get you very far)
1 bicycle wheel (found in garbage)
1 large piece of wood (to act as a base for the breather)
1 chair to sit and relax on once in a while (and also to hold the bucket at a good level)
2 bungee cords (Ill explain this later)
some string and rope
1 elastic band
a bit of odd screws to hold various things together.
bits of steel as structural support
1 weight (can be just about anything cheap and about 5 lbs)
Step 2: The Wheel
I just used some scrap steel to make a bracket to hold the wheel about 8 inches off of the base. I am cheating by using a welder but I'm sure there are lots of you out there who could rig this up without the aid of a welder.
Step 3: Turning the Wheel
Step 4: Turning Rotary Motion to Linear Motion
This is not quite liner motion yet. We need to install a pivot and a slider or piston.
Step 5: Finishing the Linear Motion
Step 6: The Air Pump
Step 7: The Jack-o-lantern
Step 8: The Video
After the video was taken the breather machine was taken around behind a shed (the vacuum hose was about 30 ft long) so the noise could barely be heard. The hose running from the back of Phil was hidden as much as possible.
