DS12 has been pining over a thing called "Ferrofluid" on the Vat19 site, so if he doesn't manage to buy it before then, he'll get that. It's "nano-sized magnetic particles" in a glass bottle.

I also found something fascinating that I plan to get both kiddos for Christmas, which I'm positive I will like and pretty sure they will like. smile It seems to be sold under different names, but the most common is Kinetic Sand.

DD8 is getting a Nintendo 3DS so she can stop borrowing her brother's.

I haven't thought beyond that yet.
