What reading level is Soap Bubles Their Colours And the Forces Which Mould Them book?
To quickly assess the difficulty of the text, read a short excerpt:
The holes come one after the other opposite the hole in the fixed card, and so at LIQUID CYLINDERS AND JETS 83 every turn six flashes of light are produced. When the card is turning 21 J times a second, then the flashes will follow one another at the right rate. I have now started the motor, and after a moment or two I shall have obtained the right speed, and this I know by blowing through the holes, when a musical note will be produced, higher than the fork if the speed is too high, and lower ...than the fork if the speed is too low, and exactly the same as the fork if it is right.
To make it still more evident when the speed is exactly right, I have placed the tuning-fork also between the light and the screen, so that you may see it illumi- nated, and its shadow upon the screen. I have not yet allowed the water to flow, but I want you to look at the fork. For a moment I have stopped the motor, so that the light may be steady, and you can see that the fork is in motion because its legs appear blurred at the ends, where of course the motion is most rapid.
