So I have slight OCD
(I would say common sense) .

Walk up to a 1970's coffee maker in any office and you will usually find it has never been cleaned.

You have Stir Sticks, Styrifoam cups, Coffee filters, and a empty cup from the gas station you stopped at you disposal.

And this simple ring.

Step 1- Poke holes in the styrofoam cup (Or paper cup)
Step 2- Insert coffee filter into hole-y cup
Step 3- Microwave a cup of water in a seperate cup
Step 3- Miix coffee grounds and water and let sit for a couple minutes (Hint turkish ground coffee is freeken amazing to use here)
Step 4- Pour coffee concoction through the filter into the cup.
Step 5- Enjoy the cleanest cup of coffee you have ever made!!!

Step 6- Hide the evidence that you have slightly killed the planet by using 2 styrofoam cups!
