And its a fact. We did that in the sixties to in school. The thing is for me in my thoughts though that came to mind:.........is that I had already done it by the time our teachers told us to save our milk cartons for the project. I had pretty much already gotten the idea from Grandma and Grandpa already. It was new to the other kids though, and I was still proud to take my bean home and add to the field because it was mine!
People spend money for bean seeds. Dried beans from the grocery store in a bag were what our teachers used to buy to teach us to grow! Cook a pot and save a few to plant.
