It's a tiny device that can keep drunk drivers off the streets.
The device is called the "BreathScan", and one a local business is now selling them inside their new bar.
At the Boston Pub, the breathalyzer sits next to the cigarettes. The bar, which is set to open this weekend, is located near U.T.S.A. and is sure to see it's share of students.
"That's the first time I've every heard of a vending machine giving out breathalyzers," said U.T.S.A. freshman Mohammad Ali. "I'd like soda from my vending machine. But a breathalyzer? I guess that's new, but it might catch on."
So, if you're having a few too many, you can easily find out.
"It's a warning sign for them that 'hey you know, I'm getting close. I need to stop'," said bartender Jessica Vaught.
The two breath scans in the pack will cost you $7.
"I would say that that's a good thing, to make sure that nobody is driving under the influence," said U.T.S.A. junior Sobe Qazi. "Cause, obviously, this is a college campus, and people do that all the time."
After you snap the tube and blow into it, the color change lets you know whether or not you're drunk.
"I would use it," Ali said. "I wouldn't want to risk my life or any of my friends life. And you know, college students always need a designated driver."
Although police don't endorse any type of breathalyzer, they do say anything that could stop a D.W.I. is welcomed.
Owners of the Boston Pub also plan on selling the breathalyzers at their two other bars in San Antonio.
The Boston Pub will also offer designated drivers complimentary non-alcoholic drinks. The bar is located at 8202 N.W. Loop 1604 West (at Hausman).
