The water filled jar rolled faster and continued to roll further. Sometimes the water filled jar would roll backwards almost to starting position.

the air-filled jar

Train, WI | Rolling Jar Race
I thought the water filled jar would win but I was wrong. Even though it had ahead start it slowed down. The air filled jar passed the water filled jar and won!

Tegan, TX | Rolling jar Race
my air jar won

Mary, KY | Rolling Jar Race
I found that the jar filled with liquid (heavier) rolled faster down an inclined plane onto a runway of smooth paper,but the jar that was empty (lighter)rolled the greatest distance.

I did not have a really big binder so I used two small ones. One on top of the other, the water filled jug won the race. I wonder if the binders made a diference? The jar with the water rolled the fastest on the binder but it slowed down alot when it got to the botom. It still won the race though. But the air filled jar went alot further.
