My son (the middle son, the filmmaker) went on a field trip last week with his class to the Rutgers Agricultural Museum in New Brunswick. Here is an old-fashioned firetruck that he photographed. (I didn’t go on the trip; he took his own camera).
Part of the reason for the trip was the boys have been studying the 39 Melachot, the 39 acts of work that a Jew is not allowed to do on the Sabbath. All of these Melachot are agriculturally-based, so their teacher used the museum as a way to show them threshing, winnowing, grinding sheaves (I have no idea what those are; I took those words off Wikipedia). Each boy had been assigned one Melacha to study in detail.
My son’s Melacha was weaving. He had already presented to the class, and his teacher told me later that he gave my son weaving because it was a more difficult one, but he knew my son could handle it. He did an origami basket project with his class. Yes, I am proud of him!
