Step 1: Supplies
Before you begin gather these supplies. Find a potato, craft/ hobby knife, rasp, and a 4-6" piece of 1" pipe.
Step 2: Bevel the Edge of the Pipe
First, you need to bevel the edge of the pipe. Hold the pipe at a 45° angle to the rasp and swipe with consistent strokes. Continue, turning the pipe constantly, until a nice sharp bevel edge appears on the end of the pipe. If you need to, you can file any burrs with an emery board.
Step 3: Cut the Potato
Next, it is time to insert the pipe. At one end of the potato press the bevel edged pipe. Turn the pipe and allow it to grind into the potato about an inch. Once it is in an inch pull it out of the potato. You should now have a circle cut at one end of the potato. Next, using the craft/hobby knife, cut 3-4 rings on the sides of the potato down to 1".
Step 4: Unveil the Cork
The next step is to remove the rings and cut your cork off the potato. If you cut consistent and straight rings, they should slide off the potato easily. If your rings don't slide off smoothly, cut more rings in the side of the potato. Pull off all the rings until your cork is unveiled. Lastly, take your craft/hobby knife and cut the cork off the potato.
Step 5: Pop on Your Bottle and Enjoy
You are finished. Pop your potato cork onto your capless or corkless bottle. It should fit tightly and seal the bottle. Now that you know how to make the 1" cork, you can try using other sized pipes to make different sized corks for bottles. Enjoy!
