First tests to check if the bags were fully waterproof.
Tests to see if the calculated amount of cork was enough to make the phone(here Iphone 4S) float.
The same test with a Blackberry.
To keep the cork and phone together we made a silicone rubber bumper.
This was first drawn out in CAD(Siemens NX 8.5).
With the CAD files we could use the lasercutter to make our mould.
Mould in place, ready for pouring.
The rubber went into some places where it shouldn't have, but this was easy to fix with some cutting and sanding down.
The cork was cut by hand and treated to make it water resistant and thus more durable.
Before the bumper had dried we could use the negative parts of the mould to check if it would fit.

Underwater Love - Fairphone cover
With the release of the Fairphone we got the assignment to design a low-tech smartphone gadget.
We decided to make a waterproof case. During research we found that most cases lacked two things. First of all: they don't float. Secondly: they are all plastic.
We used an existing bag to keep the phone dry in regular circumstances. When you're active in open water you can attach a cork floating part. A silicone bumper holds the phone and the cork together.
