The "beer goggles" simulate what it is like to have drunk too much alcohol
Teenagers in Bradford can now discover the dangers of misusing alcohol - without drinking a drop.
They are being offered the chance to wear so-called "beer goggles" to simulate the effects of drunkenness.
Youth workers are touring the district this week, telling teenagers about the health risks posed by alcohol.
Cllr Ralph Berry, executive member for children and young people, said: "They will see how drink affects balance and that their reactions are slower."
While they are wearing the "beer goggles" the young people will be asked to walk in a straight line and pick up a cup to see how being drunk can affect the body.
The youth service team are visiting several secondary schools including Thornton Grammar, Buttershaw School and Beckfoot School as well as some pupil referral units.
Cllr Imran Hussain, executive member for community safety, said: "We want to get the message across as early as possible to our schoolchildren that not only is it illegal for them to drink alcohol under the age of 18, but it can be very dangerous.
"It can make them vulnerable to attacks in the street as well as induce long-term health problems."
Pupils will also learn how to prevent their drinks being "spiked" with spirits or wine - which makes their drink stronger - or even with drugs which could make them unconscious.
The tour by the youth service team is part of Alcohol Awareness Week, a district-wide campaign to help cut alcohol-related crime and to promote sensible drinking and the work that is going on across Bradford to try and reduce the harm caused by alcohol.
As part of this, shoppers are also being asked to know their limits, with nurses based at Bradford's Kirkgate shopping centre this week available to offer free physical health checks and offer alcohol information and advice.
Rite of passage
Youngsters in "beer goggles" are asked to walk in a straight line
Meanwhile, Bradford City stars Lee Hendrie and Shane Duff are speaking out in support of Alcohol Awareness Week.
Lee said: "Enjoying a pint or two while watching the game is one of life's simple pleasures and for some it can even be a rite of passage.
"Have fun, enjoy the game but know your limits."
And Shane said: "There is nothing wrong with enjoying a drink or two, but overdoing it can cause serious and long-term illnesses.
"Our message is simple: take it easy, enjoy a drink but know your limits."
Guidelines issued by the Chief Medical Officer suggest that men should not drink more than three to four units of alcohol daily and women should not drink more than two to three units daily.
Two pints of medium strength beer or lager accounts for just over four units. One large glass of wine amounts to three units.
