I remember putting scraps of copper in camp fires as a kid.These are fun and they last a good long time. Kids think it's cool, adults probably haven't ever seen it, and it's something to do besides watch tv.
Usually $15 (I keep them on a list)
Hell yea, picked up some of those and a set of flex head metric gear wrenches from the irate store
Most or at least a lot of the Smithsonian DK books are on sale, great gift for kids. Adults too, there are a bunch of topics on history and science. We have gotten my nieces and nephews DK books on dinosaurs, bugs, cars, history of science, gem stones, and probably some that I'm forgetting.Books.
None of what I have in my Books Wish List are on sale. But, maybe others do or "must reads" that are?
