Temporary tattoo could prevent sexual assaults – by changing color | In this proof-of-concept tattoo, lettering changes from yellow to red when exposed to the date rape drug GHB
While it's very important to know if a "date rape" drug has been sneaked into your drink, whipping out a full test kit in a bar may be awkward and time-consuming. That's why scientists have developed a temporary tattoo that can detect such drugs in just one second.
While it's very important to know if a "date rape" drug has been sneaked into your drink, whipping out a full test kit in a bar may be awkward and time-consuming.
