I get a small percentage of what sale they generate. Thanks for your support! Intro: This video shows you an easy way to flatten soda cans completely and turn them into shiny sheets of aluminum that you can use in your DIY craft projects. The reason for presenting a solution how to flatten soda cans is that after recycling normally the obtained aluminum sheets keep the round shape of the can. This makes it cumbersome do work with. It is much easier to work with a flat sheet where you can transfer you design onto and then cut it out with scissors. The current method to flatten soda cans that I could find in the Internet was to bend the round sheets over a tables edge for flattening. However, I did not like the results and therefore was looking for a better way which is presented here. As an example, I attached a small project how to use the flat aluminum sheet to make a 3D-star. Thereafter it is up to you to check out paper craft books for ideas that you can realize with the flat aluminum sheet. I am looking forward to see your ideas. Step 1: Parts List To flatten soda cans, you need the following household items: • A clean soda can (you can remove the ink before or after flattening) • Knife • Small piece of wood • Scissors • Electric iron To make the 3D-star you will need additionally: • Pliers • Marker • Cardboard To remove the ink from soda cans you will need: • Pressure cooker • Nail polish remover or another solvent like Acetone, EtOH etc. Step 2: Remove the ink Before you start you can remove the imprints on the outside wall of the soda can. I already posted an Instructable that demonstrates a method for ink removal from soda cans. You can find the Instructable here: Step 3: Separate top and bottom of the soda can Clean the emptied soda can by rinsing twice with water and then let it dry. Now we start a procedure to carefully cut off the upper and lower parts of the can. Pay attention to your fingers during this procedure, as aluminum edges can lead to heavy cuts. Use a knife to mark a groove around the can. Hold the knife on a piece of wood at a level plane and then rotate the can around. It is not necessary to cut through the aluminum. Apply some pressure with your fingernail near the groove to separate the top and the bottom part (see video). Separate the tube with scissors to obtain an aluminum sheet. Step 4: Flatten the Soda Can Now comes the trick: To flatten the aluminum sheet, use an electric iron. Adjusted it to the maximum heat (Linen) and then hold it over the sheet for 3 minutes. I could not see any damage to the iron after using it on various sheets however I have to admit that the iron I use is only for waxing alpine skis. Let it cool down and the you have completely flat aluminum sheets ready for any kind of DIY projects. I recommend scrolling through old paper craft books for ideas how to use the sheets. The advantage of aluminum is that your crafts later can be put outside because it will withstand any kind of weather. Step 5: How to make a star Draw a star on a piece of cardboard. Cut out the star and place it on the flat aluminum sheet. Transfer the design by following the star with a marker. Cut out the star with the scissors. Mark even lines between the opposite corners of the star with the back of the knife. Bend the aluminum along the lines to form the star (see video).
