Yesterday my son was getting really mad about his temp in the incubator it keep saying it was 85 degrees. He fooled with it and it never would go up to were it should be. He fussed that he would loose the whole batch. So I go to town trying to find him a heating element and come back. He was still fuming and I could not find what he was looking for. I asked his older brother if he could see what was going on. His older brother turned it up and tried watching it. Then I told them to come back and recheck it.. They both started laughing and saying how dumb they were........the therometer was outside of the box not in were it needed to have been......It was too funny but great that he did not loose the batch.
