Judgement Day

Apparently, 5m wasn't the real aim, it was 3m. That's okay though because we built our car for distance. Distance is what we got alright. The first trial with the 12 inch balloon went about 15 meters and change. Our second trial with a different balloon, larger than the 12 inch balloon, carried the car passed 17m. Finally, just for kicks, we asked good ol' Aaron if we could borrow his HUGE balloon. Let's just say the Libermann record or 22m doesn't exist anymore. Our balloon car -- powered by Aaron's balloon -- travelled 28 meters*. The car went down the stairs, flipped upside down while continuing to roll, the down the next set of stairs where it flipped right side up and continued on it's merry way. Hence the reason for the asterisk, the stairs also helped us break the FLCHS distance record, which by the way could/would never be defeated because the balloon car race shall be discontinued. Good job to everyone on thier cars we had fun seeing what everyone else had done, and how they worked. It was fun and thanks Aaron and the stairs!

Sorry, we know that these aren't the best video qualities but it at least shows that we did test our car. One trail run was unsucessful in surpassing the 12m aim while the other passed the 12m with ease.

Versic 1.5 (?)

Is our notes out of order? Possibly. Are the notes still valid though? Yep! Here are some notes about our Versic car 1.5:

Purpose
The purpose and goal for our car is to travel a distance of 5m

Materials
1 shoebox
18 straws
A pair of toy truck wheels
1 glue gun
Two 12-inch size balloons

Method
The way we planned to make our balloon car was out of Styrofoam. However, it did not really work due to the size of our wheels used (we only had 1 pair of wheels). What we also found difficult was mounting the balloon onto the car
We drew up a few models and designs for Versic Car 1.5. However, we did not make them due to the size of the wheels we had and the struggle to find a way to attach the balloon. Therefore, we decided to see what ideas we were able to cook up from other people’s sites, pictures of cars, and other balloon cars we saw. There were some ideas that we liked and disliked about other cars we saw, but still struggled trying to design the car on paper. Eventually, we just decided to find other materials we had in the house, and play around with them to make a structure and body for our car, which would be light enough to move the air being shot out of the balloon so that it would travel 5m.
Another idea that came to mind was surrounding the balloon with straws by taping it. After that was done, we would use a glue gun to attach the straw surrounding the balloon to the ca.
What we finally realize was that we need some sort of compartment to attach to the car and hold down the balloon.

Observations
as we were building the model of the car, we struggled to find a way on how we can attach the balloon to the car so that the balloon wouldn’t be touching the ground and so that the balloon wouldn’t fall off
Surprisingly our car looked somewhat like the blueprints. But some of the new things we added to the design made it look a lot different because of how we played around with our ideas and materials we thought would be useful
Even though we had the model of the car finished, we still met the same problem we had with our first few designs and that was how we were going to attach the balloon to the car. We tried multiple ways on how to get that balloon to stick to the car. We tried just taping the balloon to the top. Sadly, when we tested it, the balloon went flying off. I suggested the idea to buy a different shaped balloon that was skinnier. We were able to tape it down to the car, however the force of air coming out of the car, result in the car losing speed, power, time and distance.
Our excitement was crushed when the car was unable to reach the 5m mark, only hitting a maximum distance of 4.7m. There were some minor problems found with the car, such as the wheel alignment and some bodywork. However, the minor adjustments that were made had little impact on how the car traveled.

Conclusion
Versic car 1.5 did not work because...
we were not able to find a way to attach the balloon so that we would reach the 5m mark.
wheels were not properly attached
body could have been built better (e.g. the body was not straight due to the way we cut it)

Designing and building a car takes a lot of time, effort and focus. There a few that must take place for the car to be successful, preparation of materials, measurements, assembly and trials and error. However the key to making all of these steps work is being precise with these steps.

The Calm Before the Storm

Tonight was the final trial runs before the actually race tomorrow at school. The car is painted Versic colours (green and yellow, with some purple for jazz) and is ready to go, for what we hope is a sucessful run tomorrow.

Picture 1 is the trial chart.

Styrofoam Car 2.0

Today after school, we tried out our new ultra light Syrofoam car 2.0 . It travelled the 5m but we are definate that it could go faster and further. We forgot the glue gun and so used tape. It held together but the wheels were shaky and the axel slid back and forth. Also, we tried it out on the brick floor in the hallway so the bricks could have affected the speed and/or distance that the car could have travelled. We changed up the design a bit but still kept the styrofoam idea. The materials were:

• a styrofoam container
• 2 wooden BBQ sticks/ scewers
• 4 gator board wheels (harder cardboard)
• 1 straw
• 1 regular sized ballon

We will try to upload a picture of our car later.
