Theme:

Our theme is “Lord of the Rings”

What we are aiming for :

We are aiming for design and innovation

Problems:

The rubber band was becoming too tight or too loose and so the car did not go straight and far. The actual problem was that the pully kept on wobbling, so even the new rubber bands that would fit perfectly would break. Another problem was that the car did not move straight, because the axel was not in a straight line.

Solution

Our solution was to hot glue the pully to the axel to make it rotate without wiggling and the rubber bands fitted perfectly. About the second problem, we adjusted the direction of the axel with many trials till it started moving straight

Things I am proud of

We are proud of our car design with the Lord of the Ring theme showing Mordor with Barad-dûr. We are also proud of our little succulent in the middle of the car which shows our love for the environment.

Extra

Inside Barad-dûr we kept some quarts that can make the tower buzz by putting the pipe cleaners in there.
