Make a Glad-Bag pillow with only a soldering iron, baking paper, zip-lock bag, a pen, scissors, and a paper clip. Feel free to play the MacGuyver theme in the background.
Step 1: Get Your Stuff
Materials: Zip-lock bag, baking paper, soldering iron, scissors, paper clip, and a sharpie.
This is a simple adaptation of another instructable, that was a little confusing and I couldn't find it.
Step 1: Mark a line across the top of the zip-lock bag, about an inch under the lock. In the middle of the bag, put two vertical lines from the top of the bag to the line you just drew. They should be about 1/2 an inch apart, and should form a hot-water-bottle shaped neck.
Step 2: Solder the Bag
First, put down a layer of baking paper (wax paper) on the table. Next, put down the ziplock bag, and then place another sheet of baking paper on top of this. Now, turn on the soldering iron to warm it up for a few minutes. Don't let it get too hot, as it will burn through the paper and melt through the plastic. If the baking paper turn brown, the soldering iron is too hot.
To melt the zip-lock bag, simply drag the end of the soldering iron across the top of the baking paper, following the line drawn on the bag. Don't go too slowly, as this will melt and burn the bag. Also, don't go to fast or the zip-lock bag won't melt enough to form an air-tight seal.
Step 3: Cut Off Excess Plastic
Cool beans. Now you can slowly lift of the baking paper, and expose the bag. Now, cut off the zipper of the bag by tracing around the outside of the melt-lines with your scissors. Remember not to cut off the small 'tag', as this is what is used to inflate the pillow-de-la-gladbag. If you want, you can use a straw to inflate the bag. To seal of the bag fold the end of the tag over, and secure it with a paper clip. Now the entire bag should be completely air-tight, and a heck of a lot cheaper than any travel pillows you might find.
This 'project' was basically me just practicing my melting for when i tackle something a little larger (a blow up chair perhaps...) I'll leave it up to you to think of other things you could do... other things with 'blow up' in the name... ciao
