DNA: it carries hereditary information, it helps solve crimes, and now it can act as a flame retardant? What *can’t* this molecule do? In this episode, Alex uses solutions of homemade strawberry DNA and molecular-biology-standard salmon DNA, to try and make three different types of yarn flame-retardant. The results? A potentially sustainable option for future fireproof gear!
