Want to do a cool science experiment?? Pour 8 ounces of grape juice (not cocktail... the real stuff) into a tallish, skinny glass. Set the glass in something to catch the "eruption." Add 4 spoonfuls of baking soda, and stir: Pour in 4 spoonfuls of white vinegar: Watch it erupt! The girls LOVED this... This experiment brought back sweet college memories of a prank using liquid dish soap, a garbage can full of hot water, and 13 pounds of dry ice in someone's kitchen... :)
