Thanks, Bant. I think you would be quite reasonable to not see her again, actually, for any one of the reasons you've given. You think there might be a connection though? Really? Or is it just that the dating pool might be drying up a bit and you still fancy a paddle?
My (simplistic) understanding of how microwaves work: Almost everything has a fundamental frequency, at which it vibrates more easily. Water molecules vibrate at a similar frequency to that of the microwaves. So when microwaves get going around water molecules, the water molecules resonate with them and start vibrating, and all that jigging about makes them heat up. Plates don't have much water in them, so they don't heat up themselves, but will get hot if in contact with hot food. Theoretically, I reckon a cracker shouldn't heat up in the microwave, but I haven't tested this yet.
Please, someone correct me if i'm wrong. I'd hate to be responsible for misinformation.
Last time I went to the Science Museum, there was a microwave just like mine on display.
