0113 squeezing bottle with tube closed; pressure; exit velocity of water
0115 flow experiment; energy change; continuity eqn applied to water in bottle
0122 experiment v_exit vs. t, v_surf vs. t => area ratio; applying Bernoulli's eqn; PV = n R T, PV^gamma = const.
edit
0124 expt approx. heat of fusion water; begin bottle engine
edit
0131 series of questions-answers summing up; more about energy
