An international cadre of scientists is attempting to dig through the earth’s crust and into the earth’s mantle for the first time. The attempt is being described as geology’s moon landing, and many science fans are excited for the endeavor - including your group of young scientists. The researchers are presenting their plan at a conference in Tokyo, and you have a set of plane tickets ready to take you and your friends there. Your teacher locked the tickets in a box for safe keeping, creating codes based on materials in his desk drawer. However, he absentmindedly forgot the codes! He dug through his drawer but still can't remember, and left his materials scattered in his frustration. Can you find and use the materials from his desk to open the box and get to Tokyo for the conference?
