1. Our structures were to far apart so parts would droop.
2. Our funnel bowl would last 1 second due to the friction from the start.

1. We can't figure out how to make the drop steep enough for the hill to have enough potential energy to make it up hill.
2. Most of the time, our tunnel would not work and the marble would go off the track.

# data[].attributes.body
1. We had difficulties attaching the corkscrew prototype to the coaster because design made the marble fall of the track.
2.We had trouble producing enough energy to go up hill.

# data[].attributes.body
1. It was hard to go up hill.
2. We had a lot of friction, so it was going slower than expected. We need to fix it for better velocity.

1. Not having enough energy to make it up hill, after the first drop.
2. We could not get the funnel drop to work.
