International Women in Engineering Day happens annually on 23 June. This year, to celebrate in school, we once again organised ‘The Big Build’, a fun, hands-on session in the quad at lunchtime organised and supported by our Lower Sixth Engineering Society. Balloon rockets illustrated Newton’s 3rd law (with some aerodynamic investigations included!) and geometric bubbles examined how surface tension can influence the shape, size and stability of bubble films. It was huge fun!
