Solar Cooler in a Can

Step 6: Create an Absorbent Bucket

Now it's time to finish the bucket part of the bucket. Wrap 4 to 6 towels around the inner screen that you just created and insert the sushi roll into the bucket. Stuff the edges of the towels below the surface of the bucket. Your cooler is now ready to accept a food capsule.

This looks like the perfect use for old nappies.

Ewww - old *clean* nappies, please!

Haha I used brand new bulk washcloths, but old, washed rags would be better and more "eco-friendly." Not sure what a nappie is though...

Nappies = daipers. See Ziggiau's description for more.

You know those toweling squares you fold into clever triangles to put on babies bottoms to collect everything that comes out from the bottom end? Once you're done using them for that purpose (a couple of years down the track) you're left with perfectly good squares of toweling.

Ah, diapers. We've always used disposables, which are super absorbent and have lots of other uses.

Great instructable. The ancient Egyptians used large porous (unglazed) water pots to keep water cool in their hot dry climate. Water would seep though the side of the pot and cool the pot and its contents by evaporating from the surface. Some water was lost this way but the pot could be topped up occasionally to replace evaporated and used water.

Just wondering, but would a sponge be a suitable replacement? i dont know where you'd find a sponge the same size, but still, just wondering.

Yeah I think I mentioned it somewhere in the materials section.
