- Fix our course
- Make a new one
Well, we tried to fix our course but soon decided that that wasn't feasible within the time constraints, so we had to devise a new course. Well, the mirror part was easy, just slap on a bunch of 45º mirrors and the laser should just make right angles straight across the course. Nothing fancy, no bonuses, save for using an extra mirror. But, here was the major problem. We had to include a refraction tank. As you can see, adding a refraction tank actually took math and figuring, both of which we didn't have time for because we had about 5 minutes at this point. We sat there, very close to defeat, no idea what to do, we had to add a refraction tank but it would send the laser off in some weird angle that we didn't have time to calculate. Suddenly Jake got an idea. Couldn't we arrange two tanks in such a way that they cancel out the refraction effects, thereby eliminating the need for math? Aha! We figured it out! Simply take two refraction tanks and place the flat ends together, creating a circle. That way the laser should pass straight through the center of the circle and the refraction of the two tanks would cancel each other out. Yay! We had a plan that would work! Here's the course we decided on, the brown blocks are the obstacles and the laser originates in the upper left. The blue things are the mirrors and the two half circle tanks are near the end, in case chance refraction occured it wouldn't have a lot of time to get off course before hitting the target. Well, we got to class and were super excited to have such a simple course that should be deadly accurate. Also, we were quite proud of ourselves for figuring out how to cancel out the refraction tanks, even roping in the 10 extra points for using an extra tank. Well, it was our turn, and we had 5 minutes to set up. We quickly set up the mirrors, no problem, just 45º on graph paper. I set up the tanks, aligned them so the laser would hit exactly in the center, and then we were good to go. We have to do the setup with the laser turned off and then we have one shot to just turn it on and see what happens. We were set in a minute flat. We switched on the laser and BOOM! Perfect hit! Cue me and Jake high-fiving and w00ting and generally being merry. 100 points + 10 for the refraction tank + 5 for the mirror = 115 points out of 100. Well, Jake and I were happy and spent the rest of the class period just kinda hanging out. Well, at the end of class, our teacher anounced the top three teams. We weren't one of them. Uh-oh. Teacher then reports "The rest of the groups need to redo their laser shoots because, well, you all missed the target or had some issues". Oh no you didn't! He did NOT just give us a zero on our shoot! You can bet that we complained. Apparently he was upset that we had cancelled our refraction tanks, not demonstrating true refraction. NOT COOL! He made us have to come in after school some time and make it up. NOT COOL! We got 115 points and didn't break a single rule! Grrrrrr! Well, today we redid our shoot and still used the refraction tanks to cancel each other, but now it looked more like this: I actually did calculations to make the tanks work. We hit the 100 using the same amounts of mirrors and tanks, but he only gave us a 90. That would be a 25 point deduction. NOT COOL! Grrrrrr, hence the unfiltered hatred part of the title.
