OK, how does it change colour? |
|

A nurse secretly tests you when you are not looking, and then colours in the mask with a permanent marker pen if the result is positive. That would work. |

Amazing idea if you can make it work. |

It just needs built in swabs |
|

| |
[pertinax] apparently all you have to do is to use an
'lac-galactosidase operon as the circuit
output to
hydrolyze chlorophenol red; D-galactopyranoside' |

Not sure if they tried this on madks, though... |
