Others have mentioned using an empty peanut butter jar for soaking. There are the screw top plastic storage jars by Rubbermaid and others. They are fairly lightweight. The pint size makes a decent small bowl. It would be nice if they made a 24 Oz. jar. The heaviest part of these things is the lid. It's possible to use these jars for small item storage, but what do you do with the small items while you are soaking something?
