Vinegar poppers

In science class today, we received an assignment. Before taking note of what the assignment was i noticed that on the floor was a big taped square in the middle of the room ending at the window. The assignment stated to get a cork to hit the window. Then I knew why the square was there. The only props we were aloud to use was vinegar, baking soda, a cork, and a test tube. When Mrs. R gave us in gesture that it was time to start i snapped the goggles on my face and got right to thinking. Looking back at my notes I realized that in the begging I presumably thought that if we use an even amount of both substances then all would to the window. Now looking back at it with the information i now now well of i wouldn't have chose that montage. although it is hard to get things right on the first try i did get one thing right and that was that i noted to put more pressure on the cork. 1st try was a fail of the cork succeeding to the window. Hopes were still high by second time around. Time was ticking on the clock and we were only giving so much time to come up with our next proportions and then we suddenly came up with the idea to put less baking soda and less vinegar. " come on table 4." walking up to the line having to move quick and trying to shove that cork on only made matters harder. well one thing that i realized was that you cant stop time so you have to work with it. I came to that understanding after a complete fail of hitting the window actually moving at all. the cork fell flat to the ground on our 5Th try. but still with never hitting the window we didn't give up hope. we stuck with the idea of having more vinegar less baking soda. then after we came to the ending of all of our trials we started holding the cork down for 3 seconds trying to increase the pressure. by the end we never hit the window however we did get close. I feel like if our timing was correct and angle we would of hit it. every time i said fail i met i did not meet the goal however nothing is ever a true fail unless you don't try.
