Henry's Law and Noisy Knuckles  Doris R. Kimbrough
Presented here is the application of Henry's law to the noise associated with "cracking" knuckles. Gases dissolved in the synovial fluid in joints rapidly come out of solution as the joint is stretched and pressure is decreased. This "cavitation" produces a characteristic noise.

A Demonstration of Ideal Gas Principles Using a Football  William D. Bare and Lester Andrews
A class demonstration and cooperative learning activity in which the ideal gas law is applied to determine the volume of a football is described. The mass of an air-filled football is recorded at two or more pressures, and students are asked to use these data to solve problems involving the volume, pressure, and mass of the football and the molecular weight of the gas in the ball.

The Fizz Keeper, a Case Study in Chemical Education, Equilibrium, and Kinetics  Reed Howald
The chemistry of the loss of carbonation from carbonated beverages on storage is considered. Increasing the pressure of CO2(g) will restore carbonation, but an increase in pressure adding air should not affect the equilibria. It can and does, however, affect the kinetics-the rate at which a new equilibrium is established. Thus the Fizz Keeper is effective for storage of resealed pop containers for hours, but not for periods of weeks or months.
