We first saw John Ivers in a YouTube documentary while doing research for our project. After looking into his homemade roller coasters, we decided to track him down in a single class period and find his phone number to ask for advice and questions. In 2001, he built two roller coasters in his backyard called Blue Flash and Blue Too. He is not engineering-educated (having no degrees, like us), which is why we decided to base our roller coaster cart design off Blue Flash, mimicking the 6-wheel system to help the clay cart turn and keep it from flying off the track on loops and hills. According to John Ivers, Blue Flash is his personal favorite of the two coasters. It goes no more than 25 miles per hour, which is very impressive for a homemade roller coaster. It measures 180 feet in length and the highest point is 20 feet having the highest potential energy!

On April 19, 2019, the steel roller coaster Tigris was created and opened at Busche Gardens. It was built through vertical construction, meaning "built from the bottom up or top up", just like our roller coaster was originally intended to be assembled. Tigris has a total length of 863 feet, a height of 150 feet with 135-foot drop and one inversion. Top speeds are 62 miles per hour.Tigris also has 6-wheeled cart like Blue Flash and uses the same track system. Inversion- a rollercoaster element in which the track turns riders upside-down and then returns them to an upright position

Our rollercoaster Design
materials
We used the wire to form the outer parts of the track of our roller coaster because it was the smoothest and most bendable. This made it easier to form our lengths of track and allowed the cart to move better with less friction. In addition, we used the balsa wood strips to create the support beams and the inner parts of the track, all held together with gorilla super glue (which leaves no bumps causing friction or jamming the cart). The wheels from the toy shopping cart were attached to an air-dry clay cart with wire axles

- Toy shopping cart wheels
- Gorilla super glue
- Air dry clay

Our rollercoaster design
Measurements
- The first major drop of our roller coaster should go downwards about 80 degrees.
- The total height of our coaster would be about 1 foot 2 inches
- The length of our cart going across along the bottom would be 3 feet 1/2 inch
- The width going between our coaster looping back would be about 1 foot.
- The bend/loop of our coaster would be 1 foot total (in length of the segment of track).

Fails
Failed attempts (number of times the track snapped): 16
- 04/24 and 04/26- Gabby knocked over the gorilla glue not once, but TWICE. We're not actually sure if it counts as an issue with our roller coaster so much as user error.
- 05/08- Lydia knocked over the gorilla glue, getting it on the table and her pants. We probably have to buy another bottle.
- 04/25 through 05/16- One of our main struggles was trying to bend the tracks for turns and hills.
- There were DEFINITELY more undocumented errors with our project. These are just a few with specific dates. Snapping the tracks was definitely the biggest and most common error we had in our project.
Conclusion
What we learned
1. We learned that potential energy is stored energy that increases/decreases depending on its position. Kinetic energy, on the other hand, is the energy of being in motion. Mechanical energy is produced when you use kinetic energy to create potential energy. 2. Secondly, we learned that weight is how heavily something is pulled on by gravity while mass is the amount of matter in an object. 3. Third, we learned about Newton's Laws (the first and third). Newton's first law is the law of inertia stating that "if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at a constant speed unless it is acted upon by force". An example of this is friction. Newton's third law is "every object has an equal and opposite reaction". An example of this is punching a wall. 4. One of the final things we learned is to always be aware of your surroundings!
