PRESENTATION OUTLINE
Our project was to develop and promote toys that children can use without using batteries. The gravity cruiser runs on the power of gravity using simple materials. It is easy to fix and hard to destroy.

Throughout out testing we found the medium size made our gravity cruiser go the farthest with a distance of 13ft. Using the gravity cruiser wheel test, the small wheels gave us nearly no distance at aproximitly 3ft and the large gave us aproximitly 5ft.
For our design we used a tower in the center of the chassis which made our fulcrum point near the top of the tower. We connected the winding string from the top of the lever to the transport. When we tied the string at first we used up to much time and it was difficult but we used a different approach which made it much easier.
Some factors that effected our design were the amount of pennies which we had 40 at the end. For power we moved the pennies closer to the lever.
Another problem was that the wheel would spin out but we moved the pennies back in order to have the cruiser start but not have to much power and spin out. After fixing the problem we had finished our cruiser.
