This week we’re inspired by the price of a lobster dinner fit for a king. The recently revealed price tag for President Macron’s banquet back at the end of 2023, about half a million dollars, kickstarts an Unexpected Elements challenge – can the team create something similar and manage to save not only cash, but an Italian ecosystem from an American invader?

And waste not want not as we discover how the bits of a crustacean dinner you’d usually throw in the bin may be the key to a new generation of rechargeable batteries.

We’ll also be exploring the science of spices with Dr Stuart Farrimond and singing the praises of a blue-blooded crab that’s really a giant spider, which has been helping out the medical industry for decades.

That plus many other Unexpected Elements.

Bon appétit!
