[URY914]

Here are some more details...

When we set the balls on the end of the vacuum, we positioned the valve stem on the top of the ball. Consistancy was the goal.

We marked the measuring stick in feet and inches because I didn't have a tape measure that was in meters/centimeters. She later converted the measurements to metric.

We didn't think of weighing the balls but that would have been another piece of data that would have been nice to have.

She used a composition book for recording and note taking. we dated and recorded every entry. Including notes from the very first parent's meeting we had at school.

The video camera had problems with the auto focus when the ball entered it's field of vision. We should have use a piece of 4 x 8 plywood marked with the measurements. This would have filled the complete view finder of the camera. We were limited by the amount of time when had in the building we were using so we didn't have the time to do a dry run with the camera. Next time will be different.

She had to post all the data and pictures on a presentation board and be able to be interviewed by the judges. She'll find out in a few days how she did. I will post the results (as any proud father would).
