Introduction: Cups From Cans: Instant Recycling
This instructable will show you how to make a cup from an aluminum beverage can.
Reasoning: My apartment complex does not participate in recycling, and I do not often see a process where recycled material goes from trash to goods in a simple process. So being an industrious engineering college student I thought, " I don't have any cups, but I do have cans."
So knowing the construction of the can I knew that the top hem would not be sharp and perfect as a drinking cup.
so ON WITH THE BENDING!
Step 1: Know Thine Enemy
Before we remove the top of the can we should first realize how the construction of the can allows us to do this.
Since cans are made through a deep draw process and then a hemming process the can can be carefully disassembled.
Step 2: Rip It Good
So now we know how the can is constructed, we can now rip the top off. If you can remove it in a circular motion the can will tear along its hem.
Once the top is torn off, the hem will still be attached by its lower half and epoxy.
To get the lower hem off you must rip the lower hem so it will dislodge itself from the underside of the hem.
Once that is finished you must bend the inside top flange upward and outward. Just make sure that the flange from the can stays intact.
After the hemmed part is bent upward you can peel the lower hem downward and off of the can.
Now that your Hem is off the can, all you have to do is wash it out and and remove the epoxy.
The can is finished!
Recycling at its easiest. Their also dishwasher safe!
