I'm sure just about everyone here in NA except the lucky ones in canada and the pacific nw of america are experiencing this pretty bad heat wave. I just unloaded all of my toys from storage and put them all up in the third floor (it's only one room) of my house. now there's a window at each end of the room, plus a skylight, so there's ventilation but they're all out of the direct sun. the thing is that after being in storage, I had a few star wars toys partly turn yellow, and some weapons, including a darth maul lightsaber get really warped and bent, although they were in an attic in florida, so it's not really much of a surprise. so hypothetically speaking, if your toys are out in a room where it's probably going to be 85 during the day in the summer (we've got no a/c at all) and maybe spike up to 95 every now and then, is there much reason to worry about them? I'm especially concerned with warping/melting and of course the dreaded yellowing, which even after reading threads and essays on the phenomenon, I'm still unsure of the cause.
