3 Design  Uses blue plastic tubing wrapped inside a bucket.  Ball bearing descends down the tubing at a constant acceleration.  Tubing is zip-tied through holes in bucket.

4 Stored Energy  Stored energy = mgh ▪Stored energy is the height gravity mass ▪Example: (10 g ball) ▪(.01kg)(9.81m/s 2 )(.441m)= joules

5 Design/ Construction Issues  Deciding on a final product.  Time management  Finding materials to match our ideas

6 Materials/ Tools  Bucket  Blue plastic rigid tubing  Red zip-ties  Ball bearing  Drill  Exacto knife  Duct tape  Tape measurer

7 Conclusion  As long as the ball bearing has a slight initial velocity the sphere will roll all the way down the vortex. This is also possible due to the exact differences in height as the bearing makes a revolution around the bucket.
