that bubbles were still 4visible after 15 minutes. However, from Experiment 3 we also
learned that there were no bubbles visible after 2 hours, and in Trial 5 of Experiment 2,
we saw that after the can was set aside for 2 hours, roll time went back to the baseline
speed of 1.75 seconds. 4Passage IV
