Some really cool science

This week, the Florida Panthers beat the Edmonton Oilers at ice hockey’s Stanley Cup championship, which sent us skating into ice-related science.

First up, we hear about an ancient ice skate that’s been unearthed in Prerov, Czech Republic, which sends us pondering about the physics of ice-skating.

We then discover why licking a flagpole on a chilly day is a bad idea, before delving into the science of cryopreservation.

Next up, we speak to Dr Mark Drinkwater of the European Space Agency, who reveals how satellites can help us monitor and better understand our planet’s melting ice sheets.

Plus, what do you do if you want to play ice hockey but you live near the equator?

All that, plus many more Unexpected Elements. Presenter: Marnie Chesterton, with Chhavi Sachdev and Sandy Ong Producer: Alice Lipscombe-Southwell, with Margaret Sessa Hawkins and Minnie Harrop
