Always wanted to freeze a layer of liquid? Now with the Cool Freeze Foil Box you can. It is all made out of aluminum foil and can easily be made. This box is not high tech at all but it has a useful feature, the ability to suspend ice above the liquid to be frozen. It is not entirely the fastest way to freeze a liquid but is faster than just putting a liquid in a freezer. It will not completely freeze the sides of the liquid as it is made from aluminum.

Step 2: Make Foil Strips

The first thing we need to get started is 3 foil strips. Download and print foilbox.pdf. Use the second page that looks like a rectangle with a line through it. Use the smaller width of the rectangle as a measure for the width of the foil strip that is to be made. The strip dimensions should be about 7 in. in width and a roll length. Each foil strip will make a complete foil box.

Step 3: Split foil strip in half

Take a foil strip and fold it length wise. This means fold the strip taco wise and not burrito wise. Use a straight edge to split apart the foil strip. Repeat this step until all of the foil strips are split in half.

Step 4: Fourth it both ways

The best way to fold the box is to always fold lengthwise first. Take the long length of the strip and fold it in half. Unfold the strip. Now take the edge of the lengthwise strip and fold it to the middle of the strip. Fold the other side to the middle as well. Now turn the foil 90 degrees. Fold the edge to the middle and fold the opposite side to the middle as well.

Step 5: Fold the Corners

Unfold the most recent folded edge. Fold the corner to the fold line made from the previous step. Do this step until all corners are folded.

Not to be mean but, in this Instructable, aren't you just making ice from ice?

In fact you are right. I made this instructable because the instructables I am planning on making further down the road require identical containers. I decided to publish this instructable so anyone who needs to make a foil box can do so easily. You should check out my new instructable called the "Energy Efficient Plant Supercharged". In that instructable I used the Cool Freeze Foil Boxes. The foil box was my first instructable and I wanted to see how hard it is to publish an instructable. If you use ice with the box then you don't necessarily have to use a freezer. If you use a freezer then you don't necessarily have to use ice. Thank you for your comment.
a little redundant don't you think?
