Miko and her 12-year old brother Jomo bought hot chilly pepper seeds, and planted some under a tree in their backyard. When the chillies were ready to be eaten, Miko was disappointed because they were not hot. Why were the chillies not hot? Jomo's hypothesis was that the plants were not watered enough.
