Using coffee in a talk on kitchen oceanography

I have been a bit quiet on here recently, because I had so many exciting projects going on that I did not manage to document them in real time (well, not on here anyway, but partly on my Insta).

One of those projects is on #KitchenOceanography with coffee, where I have compiled a lot of interesting experiments into a postcard. And the postcards arrived yesterday! (Thanks, Vanja, for picking them up!)

My super cool new postcards in front of the first slide of my presentation, because I had to take a picture when they arrived and that was the only background available :-D

Juuust in time for the “Hammer talk” presentation that I was scheduled to give at the Geo department of the University of Oslo. Where — you guessed it — I invited people to play with coffee!

Lots of things happening in coffees everywhere!

And I was so excited to see how well people played, and how beautiful the stratifications turned out!

Here is even an internal wave on the stratification!

Thanks for coming and for playing! :)
