T.S.B. proud partners of the Pride of Britain Awards. Hi, Katie here from the Naked Scientists.

I hope that you're all well, and that you enjoyed our show this week,

which was a recording of the live event we did

as part of the Cambridge Science Festival Festival back on the 11th of March

before the rest of the festival was cancelled.

Now here are a few extra bits from our live show

that we couldn't fit in to the main show this week, but that we thought you might enjoy, nonetheless.

behavior expert Eleanor drink water and planetary geoscientist David Rothery

and former naked scientist Dave Ansel.
