Sorry, I only recorded the 2nd Trial, and I also haven't recorded all the participants for the race day :(

RACE DAY

First of all, I would like to congratulate Ludwig and Jesse's group + Rachel and Kelly's group for both passing the 12-meter mark. Wow! I didn't really think that anyone would actually pass the 12-meter mark, but I guess I was wrong :(

I was pretty satisfied with the results of my car as it went faster than I expected compared to the other cars. But sadly, it didn't travel in a straight line. I passed the 5-meter mark in both my trials and my car traveled a total distance of 7 meters or so. Everyone was pretty surprised because of the speed of my car, they were saying that it was like a rocket :)

Overall, race day was pretty fun, because I got to see everyone's different balloon-cars and their creativity. I hope that I get more projects like these, because this project is actually a hands-on project, not like the usual projects where you collect information and put it on a bristol board... if you know what I mean :)

This is the video of my 2nd trial, it passed the 5-meter mark in under 3 seconds.. I think.
(My car actually starts moving at about o:40 seconds of the video)

Before Race Day

Okay, I'm really really nervous for the BIG RACE DAY tomorrow! Everyone has different cars, different designs, I want to see them all : )
My car works out just fine, but, you know, something bad might happen ahhhh!
BE OPTIMISTIC MAN!
I'm so nervous that I'm excited, that's how I really feel haha.

3rd Major Entry Part 2: Final Version (B2Xc - 001 Sudden)

The name for the final version of my balloon-car is B2Xc - 001 Sudden.
B2X stands for 'Bento Box', which means 'lunch box'; c stands for 'car';
001 means model # 1 and; Sudden is the car's name.

I chose 'Sudden' for the car name because I kept making sudden changes to the prototype version of the car, until I was finally satisfied with the final design.

Here is the final version, B2Xc - 001 Sudden, along with most of the materials I used.

CHANGES:
As you can see, the final version is slightly different from the prototype version.
• I reduced the number of straws by one, but I made the straw's size bigger.
• I wrote the car name just under the straw (refer to 'top view' picture)
• I changed the balloon's colour from blue to red.
• I wrapped a rubber band around the straw so that its not loose and it won't wiggle around the hole.

EFFECTS:
Changing the balloon and the straw made the final version of the car significantly faster than the prototype version. Some other changes in the design also made the car look more attractive.

Now I'm all set for race day! (which is tomorrow hehe)

3rd Major Entry Part 1: Blueprint + Prototype Version

Here are the the blueprints for my balloon-car.

Okay, here are the pictures of my balloon-car prototype version.

I don't have a name for it yet, but I have tested it already and it works out just fine.
Now all I have to do is to decorate it and make some changes (if necessary) and then I'm ready for race day! : )

UPDATES

Okay, expect the following in my next blog entry:
- Blueprint for the car
- Prototype version of the car
- Pictures of the prototype version
- Name for the car

I will post the new blog entry as soon as I finish the necessary requirements.

2nd Major Entry: Production Stage 2 (Designing Process and Materials)

Due to some material problems, there have been some changes to the body and and wheel materials. I believe that the materials I am gonna use are more efficient than the ones listed on my first entry.

Body: I decided to use a styrofoam box that I got from a Chinese fast food store for my balloon car body instead of a milk box.

I am going to cut some parts to make the body smaller and lighter so that there wouldn't be much problems trying to make the balloon car accelerate.

Wheels: As mentioned in my first entry, I planned to use the wheels from my old toy car but it seems that I lost my toy car, so I had to find a replacement. This just proves that not everything goes smoothly in life :(

These are the replacements I found, which are caps of disposable coffee glasses. As you can see, their design is quite simple so it wouldn't be that hard to attach them to the body of my car and balancing them would also be easy.

These chopsticks and straws are the materials that I am planning to us to attach the wheels together with the body of my car. The chopsticks are quite thick, so I think I'll have to peel some wood off of them to make it thinner and easier to use.

P.S. You probably already noticed, but most of the materials I am using are related to food :)
