A student filled two Petri dishes with a clear cornstarch gel,then marked the letter "X" invisibly onto the gel in Petri dish 1 with a damp cotton swab. He then placed saliva from his mouth onto a second cotton swab and used that swab to mark the letter "X" invisibly onto the gel in Petri dish 2. S Fifteen minutes later,he rinsed both Petri dishes with a dilute solution of iodine to indicate the presence of starch. The surface of Petri dish 1 turned completely blue,indicating starch. Most of the surface of Petri dish 2 was blue,except the letter "X" was clear,as shown above.
