This is what Tom is talkig about. It is better to use a glass bottle though instead of plastic for the k-meta. As you can see its a good place also to store your hoses or other small things you want to keep sanitized. Warning...caution removing lid to keep your nose away from vapors when opening.boiling will make the cork start to fall apart. Best to do what Wade does .. make a corkadore. that is add some strong meta to a bowl and add corks around it and seal. The fumes will sanitize the corks.
