We want viewers to believe our results.
So we’ll get professional

Method (same for both tests)
120 people will take the test. They will be split into groups. Each person will be
given a drink that contains:
●A fixed amount of alcohol (same as Buzz)
●A different amount of caffeine (between 0-150mg). They will not be told what
is in their drink.
They
will wait 20 minutes and then do the test again.
