šµ Ella asks: Why does our hair turn grey?

And ahead of the big day, we pay Santamory a visit to learn about the science of Christmas. This week, we're learning about Santa's sleigh... He gets to every house around the world in one night - but how does he do it and how do aerodynamics help and hinder the sleigh?
