To quickly assess the difficulty of the text, read a short excerpt:
It consists of a T-shaped glass tube bent as shown, so that the part DEF forms a small water manometer. A piece of india- rubber tubing is fastened to the branch G and its end is closed by a glass rod H. The narrow neck at B, which should be not more than 0'2 cm. Wide, is dipped into a little soap solution, and then by slightly pushing in the rod H a small soap bubble a few mms. In diameter is blown at B. The difference between the water levels in the manometer and also the diameter of the bubb...le are measured. It is found that the pressure in the bubble is inversely proportional to its diameter. Let ABC (Fig. 85) be a soap bubble and let AB be an CH. IX] THE PROPERTIES OF LIQUIDS 129 imaginary plant: passing through its centre. Let its radius be r, and let the difference between the pressure inside the bubble and that outside be denoted by p. If the surface tension of the soap solution is T then each cm. Of the thin film, which has two surfaces, exerts a force 2T. The two halves of the bubble on either side of the plane AB are therefore pulled together by a force IT x 2-Trr.
