Real Coal Specimen Set with Cotton Bag, 5-Piece

This pack of five small lumps of genuine American anthracite coal comes in a premium cotton muslin drawstring bag. Each lump measures approximately 1 x 1 x 1 inch (medium marble size). A card with a link to a science experiment for growing snowflake-like crystals on the coal is included. The experiment requires additional household ingredients not included with the coal: water, laundry bluing, non-iodized salt, ammonia, and a glass dish. This product combines novelty gift appeal with an educational science activity.
