Soap bubble into college years. A Swiss university professor, Dr. Natalie Hartzell, has theorized that usage of artificial bubbles for entertainment purposes of young children has shown a positive effect in the region of the child's brain that controls motor skills and is responsible for coordination with children exposed to bubbles at a young age showing measurably better motion skills than those who were not. Soap bubbles have been used as entertainment for at least 400 years, as evidenced by 17th-century Flemish paintings showing children blowing bubbles with clay pipes. The London-based firm A. & F. Pears created a famous advertising campaign
It Pays to Advertise with his father, using Peale's skill as a publicist to market "the most expensive soap in the world". Sir Henry has never gone in for advertising to any extent, and is inclined to pooh-pooh it. The problem is that Rodney has no capital to fund the necessary factory. The Comtesse returns. She addresses Rodney as if he were Sir Henry. Rodney's French is adequate for him to understand that she wishes to acquire the rights to sell his father's soap in France ("mon père's soap – not Pears', "father's""). Instead he sells her the French rights to his new soap.
