And here I thought the Bromine was where they dug male siblings out of the ground.

I think you may be right, Tahra. There is some evidence that yellowing happens even in the absence of direct sunlight, so heat is a good candidate. The yellowing is caused (I read) by the migration of Bromine atoms to the surface of the plastic, something which an increased temperature would almost certainly accelerate. (The Bromine is part of an additive used to reduce the flammability of the toys).

Right... will wait.... Thanks :)
