As a highly underestimated part of the body, nails feature a perfect surface for speculative prosthetics,
experimental enhancement and social exploration.
Nails can be much more than a colorful extension.

While working on the TOTAL RECALL NAILS at Science Hack Day Berlin, we invinted the PISS NAILS!
With these nails you can test the pH of your pee while peeing. It is a useful tool to be in control of your body.
The pH of urin between 6,2 - 7,4 is normal. A pH under 6,2 is a sign for hyperacidity.
