CROWDSCIENCE: WHAT MAKES THINGS BURN?, 8.30PM, BBC WORLD SERVICE

FIRES have raged through Europe during the long hot summer, devastating lives, ruining crops and disfiguring the landscape. Too many people have had to watch their homes go up in flames, leaving them to sift through the ashes for the remains of their lives. In this week’s edition of the programme that answers listeners’ science queries, Alex Lathbridge hears why substances react to extreme heat in different ways, learns what actually happens inside a material when it’s burning, and finds out how scientists are working on new, fire resistant materials.
