Imagine a 可 can of liquid with a huge 丁 spike in the middle to close it shut. It looks so difficult to open you doubt yourself. "可 Can I really do it?" you hesitantly whisper. Still, you grab the 丁 spike and, with determination, tear it out and away from the 口 mouth of the 可 can to open it. Carbonated liquid spouts forth in a fountain of victory! You 可 can open the 可 can!
