Original Design
The original design did not allow for the cap to bend easily. This would make creating a mechanism to remove caps to be difficult. We need a new design for the cap that allowed for easy bending and durability.
Testing
We made caps based on the original design and grinded them down to achieve thicknesses that would allow for easy bending. This was accomplished with the use of a circular grinder in the lab.
New Design
Our new design is a cap that tapers from the edges inward. This allows for the cap to maintain strength over time and bend easily for removal from the tubes.
