In this challenge we had to design and build a device or vehicle to move a small figure as far as possible, on fishing line, across the room. One person on the team maybe initiate the movement of the device or vehicle but may not provide forward momentum. You had 5 minutes to brainstorm, 10 minutes to build, 1 minute to test, and 5 minutes to redesign. The equipment you were allowed to use was pencil and paper. the materials given were 1 sheet of card stock, 2 tongue depressors, 2 paper clips, 2 rubber bands, 1 straw, toilet paper roll, 1 balloon, 12 inches of string, 6 inches of masking tape, scissors, and the small figure. I learned during this challenge that you need to ask all questions before you start building your product so you don't design it one way and it won't work because of other constraints you d didn't know.
This is the cable car we made out of the given materials.
