New York Academy of Sciences Children's Science Book Award Winner Vicki Cobb has a new volume called "See for Yourself: More Than 100 Amazing Experiments for Science Fairs and Projects (Second Edition)
Actually, it isn't entirely new. It's a second edition, but updated.
This is for 10 year olds and up, and it does in fact have 100 ways to make glue, fake old documents, extract DNA, do interesting anatomical experiments like finding your blind spot, produce your own ink, hypnotize your friends, make crystal flowers, etc. etc. all with common household ingredients.
It is paperback, richly illustrated with fun pictures, inexpensive and the stuff looks mostly like it woudl work. The perfect gift for the 10 - 12 year old (though I'd go as young as 8, franky) who has everything, especially those who might be far away because a book is easy to ship.
