Open doors at our PHYS labs: Usually we analyse environmental material to answer geoscience questions. On Thursday 9 March we prepared a special “show-and-tell” with examples from everyday experience.

Smells – Can your nose beat the high-tech analytics?

Try to identify the natural biological substances by their scent!

Salty fireworks – how salts color flames

… and how we use it to quantify chemicals.

Liquid nitrogen cools ethanol – and then dissolves shell material

Same same, but different – how different waters makes different coffee

… and fresh hot waffles were offered.

Thank you all for coming!
