Marble momentum

This term I was battling a nice tropical head and chest cold. Devoid of energy and lacking much in the way of voice, I put directions on the board. I opted not to lead off with a demonstration - making this term different from prior terms. I did not run my usual "how does the penultimate marble know what to do" patter. I did have to adjust from groups of two to four to allow each group to have two stopwatches, a recorder, and a marble pitcher.

The directions were minimalist at best, and this term that seemed to work just fine.
