Last Friday, Mr. Wong's 6th period class attempted to use our knowledge of gas laws to launch Coke and mentos rockets. The reason a rocket like this would launch would be because of a physical reaction. I call it this because during the reaction the coke remains coke and the mentos stay mentos. When the mentos go into the Coke, they make the coke fizz excessively with CO2 because the Coke is carbonated in the first place. Because of the cork sealing off the exit for the CO2, the pressure builds up in the bottle until it bursts through cause the rocket to take flight. At least this is how it is supposed to work. Our rocket did not have such a glorious launch. As you can see in the video below, we sealed the bottle so tight that it couldn't burst without Mr. Wong throwing it into the air. When he does this the angle of trajectory goes from vertical to horizontal and we are unable to really tell how high our rocket could have launched. When it comes to gas laws, my group believes boyels law was in effect, because the P1 and V2 were represented by the coke before the montos, and then after the new P2 and V2 were discovered. For next time, I think it would have been better to tighten the cork just enough but to much like we did in our first attempt. This would allow the rocket to shoot up by itself without outside assistance, hopefully improving the height reached.
