Kids Drink Windshield Wiper Fluid at Arkansas Day Care

Only one child remained hospitalized Friday morning, after blood samples showed "measurable levels" of methanol, a highly toxic alcohol that can induce comas and cause blindness, officials said. The day care also provided the fluid for testing.

"All we know was that the individual at the day care had recently shopped and had come back to the day care with a lot of different products," James told The Associated Press. "This product was mistakenly grabbed and thought to be Kool-Aid and put in the refrigerator."
