So apparently Sainsbury’s have changed the design of their herb jars but the new jar doesn’t fit in my herb rack. Fear not, being the problem-solving scientist that I am I cunningly started transferring the contents from the new jar into the empty old jar. The contents of the new jar supposedly weigh 12g, while the old jar supposedly contained 14g when full. However, the old jar is full and there is still a considerable amount left in the new jar and even after compaction the old jar is full to the very brim. Somehow I must have broken the laws of physics and generated mass. Either that or Sainsbury’s are lying. I smell oregano.
