There's a lot of chemistry and physics in the kitchen and this neat kit brings together - vinegar-fueled rocket, volcanic lava, lemon clock, fingerprint kit - with instructions and discussion. You can buy many of the items separately for about $7-$10, but this kit combines them all at under $30. Great for 8+, or the inquiring , questioning mind. Doesn't need parental help, but you'll get much more out of it with parental involvement. Parents can learn new things too! Box 21 cm x 17 by 6 deep.
