PALM BEACH COUNTY, Fla. — For a summer treat, it doesn’t get much cooler than -320 degrees. That’s how cold liquid nitrogen is when it transforms cereal into "Dragon’s Breath."“The vapor coming out of your mouth is a nice effect," said Ron Daranty, who owns Subzero Nitrogen Ice Cream in Parkland.However, a mom in St. Augustine is warning parents of children with asthma about the fad food after her son experienced health issues from eating Dragon's Breath.“We’ve sold thousands of them since January and we never had any issue," Daranty said.Subzero employees in Parkland have always warned people to be careful with the very cold cup and avoid drinking any excess liquid nitrogen, Daranty said. But now they've added on a new disclaimer."Even though that lady was sharing the article for others that may have respiratory challenges, I thought it was great and we added it to our sign of caution. We also started making people aware of it," he said.The risk of ingesting liquid nitrogen is purely scientific. Chris Pait, of the South Florida Science Center in Palm Beach County, said the extremely cold temperature can give people frostbite in their mouth or lungs."It can evaporate away in your mouth, but if you breathe that cold air in, there’s a chance that it’s cold enough to freeze the water that’s in your lungs," Pait said. "Your lungs are a mucous membrane. They need to be moist to work the way they should, so if you freeze your lungs obviously that isn’t a good thing. That’s going to cause problems. It’s almost like frostbite internally rather than externally."That’s why the science center shows off the power of liquid nitrogen in a controlled demonstration where professionals use gloves and goggles while handling liquid nitrogen. They show children how it can freeze a balloon, send a plug flying off a beaker, and, of course, make ice cream. But they serve that ice cream in a way that's safe. “When we do ice cream, the nitrogen is just there to freeze the liquid into the more solid form so by the time they eat it, the nitrogen is gone, it’s evaporated away," Pait said.Daranty said employees are specially trained on how to handle liquid nitrogen. People who don't want to try Dragon's Breath can still enjoy regular ice cream Subzero makes using liquid nitrogen."We’re pretty cautious about it. We understand the risks with it. Corporate has standard operating procedures and we’re pretty cautious. Everyone here knows how to handle the nitrogen. 2503

Police in Bismarck, North Dakota, want to put AR-15 rifles in some schools so school resource officers can respond more quickly in the event of an active shooter.Police asked for almost ,000 in their 2019 budget request to buy the rifles, heavy body armor and bleeding control kits for the city's nine high schools and middle schools, Bismarck Police Chief Dave Draovitch told CNN.The money will also be used to buy a safe at each school to keep the equipment away from students, teachers and staff."The SROs (school resource officers) will be the only ones who have access to this equipment," he said.The cost would be split with the school system."Hopefully we never find ourselves in a situation of an active shooter. But if we do, we really want to make sure that our SRO's are equipped with the tools that they need to do their job effectively," Bismarck Public Schools safety coordinator Becky LaBella told CNN affiliate KFYR.Draovitch said Bismarck school resource officers are police officers and are trained to respond immediately to stop an active shooting."Whatever they have to do to stop that threat, that's what we expect our officers to do," Draovitch said.They keep AR-15s and the other emergency equipment in their vehicles, but that's not as useful if there's an active shooting situation inside the building."If something happens they're not going to have time to go running out to their cars," Draovitch said. "All we're trying to do is make it more accessible so they can get to it more quickly."AR-15s are lightweight, rapid-fire rifles. Besides being used by law enforcement, the guns have been used in some of the most notorious and deadly mass killings in recent history.Draovitch says having the bleeding control kit -- which has tourniquets, gauze and other supplies for treating gunshot wounds -- could be the most important part of the plan."If, God forbid, something does happen, getting aid quickly is going to be key," he said.He said city officials began discussing the plan after the February 14 shooting at Marjory Stoneman Douglas High School in Parkland, Florida, that killed 17 students and faculty."After that happened, we really got to talking with our schools about what can we do better, what can we do differently," Draovitch said.The city will vote on the budget next month and Draovitch expects it will pass. If the money is approved, they will get the equipment in January."We're just trying to plan for the worst and we're always hoping that we never have to use this stuff," Draovitch said. 2569
