For the second Experiment, when the student squeeze the bottle, he will increase the pressure of the gas in the soft drink, which makes the bubbles to grow and some will appear. This is because the squeezing of the bottle has tend to increase the motion of the gas in the bottle, which made the pressure to increase, and more bubbles to appear.
Explanation: bubbles in a drink is as a result of increase in the pressure of the gas in the drink. This gas will rise to the top of the bottle, as their want to escape from the bottle, their will rise with some portion of the drink, which we see as bubbles in the drink.
