This challenge involved the students creating and making a cereal box marble roller. The challenge starts with the students bringing in a cereal box from home. From there, the rules are simple; you can only use the cardboard from the cereal box, 30cm of masking tape and a pair of scissors. The task is to make the slowest possible marble roller. But how do you do this? What are the things we need to focus on? How might we design a slow marble roller? Your task tonight is to design, build and test the slowest marble roller you can make. Record how long it takes, then redesign to see if you can make it slower! You have about 20 mins to create. Good Luck!
