This is Piaget’s conservation of volume test. I did this experiment at school (we went to the elementary school next door and ran tests on the kids). Most of the kids said the higher one held more liquid because it was ‘taller’, though some said the short one had more because it was ‘fatter’.
Pre-home internet I remember running a line-in to my soundblaster card from a clock radio and recording Tool’s Sober to my HDD.
The wav file took up a good chunk of the HDD. After a good amount of funking around with encoding it was barely comprehensible and still took up too much room. Was exciting and felt like a glimpse of the future.
