Bizarre Stuff You Can Make In Your Kitchen 
"A sort of warped semi-scientific cookbook of tricks, gimmicks, and pointless experimentation, concoctions, and devices, using, for the most part, things found around the house." The chemistry section includes classics like glue from milk, humidity indicators, slime, play dough, invisible ink, stupid egg tricks, crystal gardens, and electric lemons.

Crystal Recipes These recipes for growing crystals and crystal gardens are a great way to spark a child's interest in chemistry. The alum, salt, sugar, and Epsom salt recipes can easily be performed by children with supervision, but don't let them handle the moderately toxic potassium ferricyanide, copper acetate monohydrate and calcium copper acetate hexahydrate crystals and solutions.
