Ink on watercolour paper
University of Oxford Department of Engineering Science Collection
On 19th March 2018 the artist observed a live test from the Thermofluids Laboratory Control Room at the Department of Engineering Science. The test involved extremely high pressures and temperatures in the test tunnel, as air was released at 15000 metres per second producing a sonic boom. During the test Hammersley drew the scientists at work. Faced with the challenge of making a piece of artwork about something too fast for the human eye to see, she experimented with timed 15-second ink drawings in the studio to capture the sense of heat, pressure and movement during the experiment.
