"This material, which is still in the concept stage..."
That's ridiculous. How is this different than sitting around bullshitting with your friends about how cool it would be to have flying cars? "Wouldn't it be cool if you had a condom that changed color when an std was present?"
And hey, look at that, they've already picked the colors!
This is absurd for so many reasons.
1) as most people familiar with condoms would recognize, when a condom's in full use it's quite frequently dark and/or not exactly exposed to where you can see it.
2) I'm not really interested in using my dong as the dipstick, no matter what it's sheathed in. I'd really rather know the STD status *before* the dick goes in
3) considering the really rather astonishing materials science behind the construction of condoms, it's not like one can easily mix in additives - anything that's going to be part of the latex but isn't directly contributing to strength is going to be a weakness. And what are its ongoing effects on the latex over the long shelf-life and sometimes difficult storage conditions (ie wallet for far too long)? You going to use such a condom if the failure rate is 2x-3x that of normal condoms?
4) the "magic" substance that changes colors in the presence of an STD has YET TO BE INVENTED.
Christ.
