The above quote is from Tom Parr (Grad School 1966). Read the full memory below:

The Rock and it’s stairwells were apparently built with a new technology of the day in mind – the perfect place to test super balls, They bounced so well that one could, with good aim, throw a ball from the top floor all the way down to the bottom and have it bounce off multiple walls before successfully returning to the top – a favorite study break for a number of BPOC members in the mid-’60s.
