We are eating crackers during our morning break, when my colleague asked me why crackers have holes. I look at the crackers and there's many holes in it. It's thin and crispy. My son's nanny used to work at biscuit manufacturing company so I told him I will ask her. But then, it seems my curiosity could not wait until I go home that's why I googled it. I found out that holes are intentionally put there to bake the crackers properly. Crackers are made of dough that is rolled flat in sheets and these will passed through a machine containing docker pins that will create the holes on it. The holes will let heat flow through the dough producing the cracker's hard texture and crispiness. Not only that it contain holes because there should be a specific number of holes for a particular shapes and size of biscuits. Now I know why it has holes so that when my son ask me why his biscuits has holes, I can answer it correctly.
