Cassandra beamed at the professor, her hand high in the air and stated, "Cutting open a tea bag won’t work, as the leaves in a tea bag are often ground into a fine powder and will be unreadable in your tea cup. Hand-rolled teas are ideal. Not to mention the paper used for tea bags is usually bleached. Chlorine bleaching of paper, including tea bags and coffee filters, creates a dioxin chemical residue in the paper and waste water from the paper mill. Dioxin is a known potent carcinogen that we want to avoid in both ingesting and in reading, as it alters the consistency of the leaves."

Cassandra smiled as she put down her hand.
