"The Super Stay Cool Collar"
My wife who is a few years older than me has been going through some issues where she gets hot all of a sudden (even if the AC is running full blast) I talked her into trying this and she loves it for those occasions, so she told me I should update my instructable to include this side effect so that women out there having the same issue might get some relief. As a husband I'm happy it helps cause I don't have to sit here dressed like an Eskimo in the middle of the summertime just to be supportive.
Pics:Trying to get my 13 year old daughter to model the necklace in a picture for my instructable, yeah it's like pulling teeth, mine!
Step 1: Materials and Tools
Plastic Tubing (size is your preference, someone I know works at a place where they throw tons of this unused stuff away)
Water (just a couple of cups from the tap will do)
Spirits (Not the kind that goes Boo, Vodka, tequila, or just booze of some kind, the higher the proof the better)
Old burnt up hard drive (?)
Tools to use:
Dremel and cutting disc's
Various screwdrivers (hex, security star bits)
Oh yeah, you also need a freezer, or a Coleman cooler full of ice!
Step 2: The Cut Up
While this is a 3/8 diameter tube it can stay cold for about and hour, If your going to be camping, hiking, mowing the lawn it's probably a good idea to make a few of these so you can keep switching them out and re-freezing them as they stop working. A larger diameter should reasonably stay colder a little while longer.
Step 3: Time to Wax (Poetically? No Just Paper) and Turn Up the Heat
Step 4: The Mad Scientist in Me
Once you have thoroughly mixed your concoction, simply fill up the tube to the point where you'll leave the same amount of empty tube as your sealed end. Hold it up and look for leaks in the sealed end, None? Great?
Public Service Message:
Don't drink and build this instructable, this could lead to nasty burns. Not to mention poor workmanship!
Step 5: Seal It, Forever!
Step 6: Hard Drive? What For?
Tearing apart a hard drive is a very simple process remove every screw you can find pull of the outer cover locate the magnets, found behind the actuator arm. Remove the screws from the retaining bracket and the center screw from the actuator arm the magnets should lift straight out, Remove the magnet from the bracket and viola neodymium magnets.
Save the shiny platters for a future project I'll be posting soon.
Step 7: Slip and Seal
The final step in building the collar is to slip your newly acquired magnets into each end of the unsealed portion of the tubing. Take a heat gun and melt the plastic around the magnets seal them in, and your done. Tips: If your tubing is smaller than the magnets use a Dremel and cutting disc to shape the magnet to fit, or you can heat up the the tube and stretch it to fit careful not to split the tube.
Why magnets? Why not just seal the two ends together? Safety, of course, in case it get snagged on something it'll simply break loose stop the chance of being choked.
Step 8: FREEZE FRAME, Now Freeze!
The fun part begins, drop your new Super Stay Cool Collar in the freezer or cooler full of ice, then hurry up and wait! After a couple of hours it will gel up leaving it flexible enough to drape over your neck and keep you cool on the hottest of days.
