Prodedure: have person 1 roll around on unvacuumed carpet in clean black shirt, count/document the number of hairs on shirt. vacuum the affected area of carpet with dyson dc14 animal hair vacuum. have person 2 roll around on the same area of carpet in a separate clean black shirt that has just been vacuumed. count/document the number of hairs on shirt.
