Do you go fishing or camping. Then this project is for you.

Step 1: Materials

1. 2" PVC pipe

2. 2" PVC pipe cap

3. PVC Cleaner

4. PVC Cement

Step 2: Cleaning

Clean the inside of the cap and the outside of your pipe. Attach the cap to the pipe with some PVC cement.

Step 3: Filling

Fill the pipe halfway up with water. Then attach the other cap to the other end of the pipe and let it dry for 5 minutes.

Step 4: Freeze

After the cement drys put in the freezer until frozen then you're good.
<p> ok um way to many negative comments on this it is actually a very great IBLE! Well Done. A few ideas</p><p>A.) instead of water you could use an inexpensive but high proof alcohol. or isoprofol(sp) the fluid would then stay liquid and you might have a fuel source if for some reason you needed to make a fire in a hurry. </p><p>B.) instead of PVC you could just use hose barbs and caps and use flexible tubing so that you could bend the ice pack into different shapes before freezing. </p>
<p>But how do you administer these to the polar bears?</p>
Rectally
<p>I've seen these elsewhere, filled to 90%. I'm sure someone has written the expansion size of water somewhere :)</p><p>Also saw some recommendation for salt water, as it apparently freezes lower and takes more energy to melt. </p>
<p>You can custom fit them to your ice chest so they wouldn't waste as much space.</p><p>The only disadvantage that I see, is there isn't as much mass? as a jug, so I would think they would melt faster/not last as long?</p><p>Also, if you fill them with a salt water mixture they should stay frozen longer.</p>
<p>What makes these better than filling a bottle and freezing?</p>
<p>I think the advantage is that you can cut the tubes to custom fit your cooler.</p>
<p>This ible came from http://www.sheltonproducts.com/Coolertips.html , which is a site run by a guy named Bill Shelton. His intention for the tubes is as a substitute for ice in your fishing cooler. I suppose it may work to keep your drinks cool also.</p>
<p>I like it - very makeable. But what is it's main purpose and what does it do better?</p><p>Thank you!</p>
<p>so you just made an icepack to keep your lunch cool?</p>
<p>haha thats what i was thinking</p>
Intruiging..... However, you didn't state the purpose of the device. What is the purpose?
<p>These are heavy sticks that you can use to defend yourself against a polar bear or grizzly bear attack.</p>
<p>i will keep polar bears away from your lunch :-)</p>
<p>polar bears are scared from hell when they see a white tube</p>
