I'm not sure if this is the right section to post this, but not sure where else to post.
My son got a bacteria farm for Christmas, and one thing we need to provide is "broth". I'm assuming we need some sort of nutritional broth (which I determined by googling), but I can only find huge tubs of it for sale, and we only need. Few spoonfuls.
Does anyone know if there is something I can use for broth, which I can easily source? Or anything else which will work in its place?
