Do you hear this question a lot? I found a creative answer from a guy on the internet. His handle is Chuck E. And I could not email him. However when someone asks you this question then you can give them an answer like this.
You’ll need a lot of cans, like, at least a couple of hundred. You could probably get more bang for your buck if you get flavors that no one wanted, like maybe cream of celery, but you might have trouble filling it to the top if you don’t have good seals because the cheap ones are watery and easily leak. A broth, or maybe chunky style might be better if you suspect leaks, especially around the bottom of the door frames.
