At 3.32pm on Monday August 6, over a hundred people in the Museum’s Coles Theatre erupted in cheers as word came through on the live feed that we were watching from the mission control room at NASA’s Jet Propulsion Laboratory (JPL) in California that NASA’s latest Mars explorer, the Curiosity rover, had landed safely.

Penicillin mould from Howard Florey’s laboratory

Penicillium notatum samples. Powerhouse Museum Collection, object 99/30/1.

These two historic petri dishes are on display at the Powerhouse Museum during Ultimo Science Festival as part of the Science Snaps activity. The sample of green penicillin-producing mould on the left grew for one day and the one on the right for four days. Letters that complement the samples provide glimpses of the 1940s penicillin research project led by Australian-born scientist Howard Florey at Oxford University. They also give us some insight into the hardships faced by families in Britain during and after World War 2.

B1258 Velocipede Collection: Powerhouse Museum

This early pedal bicycle is a good example of a velocipede or boneshaker. It is on display in the Powerhouse Museum during August 2012 as part of a small exhibition titled ‘Bicycle: simple idea, complex evolution’ that I curated for the Ultimo Science Festival. Eight bicycles tell the story, starting in 1817 and moving through to 1994; bicycle innovation did not cease with the first pedal bike, the magnificent penny farthing, or even the modern-looking safety bike of 1885.
