Final Videos

First we have our original video of the roller coaster working that we had just in case something went wrong.

But then we decided to make one that is better quality and included the extra part that we added onto the roller coaster.

Score and Final Look

Two open loops both about 14.5 cm each

One open loop 8.5 cm

One open loop 13.5 cm

One open loop 8.5 cm

The final score is calculated by multiplying the Vertical Drop(90cm) x Time(est. 10 - 12s w/o extra) x Loop Score( (14.5 + 14.5 + 8.5 + 13.5 + 8.5) * 1.5 for open loops) x Number of Loops
So our final score would be 90 * 12 * 119 * 5 = 642 600 without the extra part included.
Our final score using the shortest time (10seconds) we've had is 535 500.
Our goal was 300 000 or above.

Day Eight

Since he already had a plan from the day before we thought it would be an easy day. I suppose it would have been if we did not have to go to home depot again, and if the extra part was not so hard to make. We ended up getting extra screws at home depot since the pack of 100 we already used up, but the screws didn't work good so we used nails from before. We found that building extra on top of an already built roller coaster was just annoying. At least we were finally done with the entire roller coaster!

Day Seven

Today we thought was going to be our last day. We had a bit of time making the finishing track for the end of the roller coaster. We decided it would be easier for us to end the roller coaster with the marble just going to the middle of a few circles. We used that idea because it was the only way we could use the little space we had left. Finally we tried the roller coaster and took the score and we got about 500 000 points. But this was when we had around 12 - 10 seconds for total time.

It was finished but with such a low time we knew we had to add more to it for it to be considered really good. So we came up with a plan for the next day and it would include building a piece and adding it to the top of the roller coaster so that it could at least add on a few seconds.

Day Six

Today we spent most of the time just making loops. We managed to make 3 more loops and a turn that is going to lead our track to the finish of our roller coaster. It was a pretty easy day since we were getting the hang of making our roller coaster and also because it was working every time we tried which really motivated us to work. It took us a long time to make a small part of the track but it was pretty rewarding which made us work harder. At the end of the day we had finished more than what we expected to.

Day Five

Today was a bit frustrating as when we drilled through the board the holes came out to small when we tried putting the track through but it was only too small by a couple of millimeters. But even though it was such a small thing it didn't let the marble go through at all. We spent about 30 minutes trying to drill without damaging the track since we had already screwed it in place. The spiral downward took a bit of time but we finished it early and decided to call it a day after that since we were pretty frustrated at how long the roller coaster was taking to make.

Day Four

Today we decided we were going to sit down and get some work down. We built the roller coaster by having one person hold it in place while the other person used the wood and tools to screw or nail it in place.

It is actually starting to look pretty decent since we made a double loop and we also decided that for the next day we will make the roller coaster go through our back board and then come back out. We also painted the roller coaster to make it look like a building, so that it will look like the roller coaster is going through the building.

Day Three

After our fail track using electrical wires we decided to finally go to home depot and get our hands on some tubing for the tracks in stead of wasting our time with wires.

This was what we decided to use after a lot of trial and error. When we untangled it we realized it was hard bend but we still tried to hold it in place and imitate the shape that we wanted of our roller coaster. It seemed to work out pretty well when we tried, so we decided to call it a day after having some success with the new tracks. We also got spray paint to make our roller coaster not look so generic.

Day Two

We gathered materials for the roller coaster and decided that today we were going to make something. James put together a bunch of electrical wires for the track in hopes of it being easier to make and more flexible than some of the things that we saw before from various websites and other roller coasters on display.

We also took some photos of what we worked with, none of those wires could do the job right. In the end of the day we really think now that we should just go to Home Depot and buy some sort of tubing.

Again this was an unproductive day as we accomplished nothing and the things we did accomplish did not work out the way we expected them to. And so we ended the day with some delicious bowls of noodles.

Day One.

    For our first day we basically just spent most of the time figuring out what we were going to do, how we were going to do it, and what exactly we were going to use. This is most likely the most unproductive day we ever had although we did decide on what we were going to try using for the track of the roller coaster.
    We thought that it would be easier to just use things that we can find around our houses and garages since then we would not have to go to the store and get anything. So we decided that for Day Two James would try to make a set of track for the roller coaster using electrical wire and we see how good it works or whether it evens works at all.
At the end of the day we realized we really did not accomplish that much at all and that for Day Two we really should try and do something otherwise we might be in trouble. Also here is a really rough sketch of what our roller coaster should be similar to, we are hoping for around 8 - 10 loops with a time of at least 20 seconds that way there would be no chance our score could be under 300 000.
