Excerpt from:
Instant, Instant Coffee - Video

On the eleventh day of Christmas, Chemistry World brought to you, the penultimate day of the quiz. And straight in with the first question.

In January, we found out that the caffeine levels in espresso coffees purchased from many coffee shops are well above the recommended daily allowance for pregnant women set by the Food Standards Agency in the UK. What’s is this recommended daily allowance for pregnant women?

Which explosive compound would you find in small amounts in your Christmas cracker? 

And now on to the answers from yesterday’s quiz.

It was Lee Cronin‘s group at Glasgow that printed their own labware.

John Millington gave the first ever Royal Institution Christmas lecture in 1825.

See you all tomorrow for the final round!
