rolls(?cylinders?) of solid glue. I've put them into my safekeeping until I went to Shivani's house. At her home, we got started on creating the mini prototypes and then to the actual vehicles.
Our choice of materials were toothpicks and using CDs as the wheels. There are some pros and cons to these items.
Pros:
- vehicle will be light and will have a very small intertia
- less resistance to movement/change
- can possibly travel far
- wheels will be sturdy
- won't break easily
- small air resistance
Cons:
- structure may be too light/weak
- could fall apart/break
- toothpicks don't have much mass
- small momentum=inability to travel far
- CDs can't travel
- not enough friction to even move across tiles
Some problems were occured during this meeting. One would have to be the glue that kept--accidentally-- burning us, causing our hand to shake, leading to the breakage of toothpicks. The dried glue strings were also a hassle, but were capable to being used as "ropes" to tie corners of toothpicks together. At this point, the thought of using pencils being the structure and axels of the vehicles was vaguely considered.
