Step 2: Preparation of the Can
Now comes the Hard Part. First, you need 8-10 holes in the side of the can, preferably about an inch above the bottom of the can. I clamped the can into the vice, then made four holes, two pairs of two across from each other, to form an "X". Then, I made four more holes, halfway in between the first ones. It isn't too important that they're all on the same level so much as it does that there are enough to allow ample amounts of air to come in.
Now comes the Hard Part part 2. On the bottom of the can, make an "X" of four marks, equally distanced from each other. Then make four more marks, each one midway between two of the original four. On the bottom of many soup cans, there are 3 or so rings. I decided to make the air intake holes in between rings 1 and 2, and the leg holes in between rings 2 and 3. However, if I were to do this in the future, I would put the air intake holes inside ring one, to allow air to get to the center more than the sides, the sides are covered by the side holes. Additionally, for the leg holes, ring 3 was raised slightly above ring 2, making tightening the screw and getting it straight somewhat of a problem. I solved this by pushing the screw and nut into ring 3, making a dent and making things a bit easier.
