Sometimes near the end of a roll the marble would roll sharply to the side or stop and roll backwards.
How far does the marble roll before friction brings it to a stop.
He played with it for days.
Due to conservation of energy the marble can never go over a hill higher than where it started.

Good science fair projects have a stronger focus on controlling variables taking accurate measurements and analyzing data.
You can build one just for fun or do this as a science fair project.
Keep the tube at a low angle to start with.
Marbles roll away when you don t want them to if there is any slant to your table.
To make my measurements relatively accurate i marked where the marble stopped rolling forward.
