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

OXON HILL, Md. -- For sisters Nikki Howard and Jaqi Wright, life comes down to a handful of ingredients.”Love, peace and cheesecake,” Wright said.It’s cheesecake that started them off on a new journey, while the two were furloughed during the federal government shutdown two years ago.“We went through the holidays just praying that it would let up,” Wright said. “And it didn't.”“So, for New Year's Eve service, I made sweet potato cheesecakes,” Howard said.Wright continued, “She gave them to me put it in the fridge. I had no idea, until I asked, ‘Who made those?’ And she said, ‘me.’”Howard said her mother and Wright began eating some of it, before her mom declared, “she said, ‘it's so good you can sell it,’ and light bulbs went off.”That is how their small business, called “The Furlough Cheesecake,” came to be. At first, they started by simply selling them online, but it quickly snowballed from there, right into area Walmart stores.“I had no idea that that one cheesecake would change everything,” Wright said.Now, they’re going a step further. At National Harbor near Washington, D.C. they just opened their first physical storefront.“So, we started our business during a furlough and we opened a store during a pandemic,” Wright said. “It makes us sound crazy, honestly, but it just happened this way.”They are fortunate. The pandemic is hitting many small businesses hard and Black-owned businesses especially so. According to data from the U.S. Census, compiled by economists at the University of California - Santa Cruz, between February and April, the number of African-American owned businesses dropped by 41%. Economists now estimate half of all African-American owned businesses may never reopen from their COVID-19 closures.At The Furlough Cheesecake, they know timing is everything.“We just took a leap of faith,” Wright said.Faith that has guided them through two – separate – tough economic times.“There's so many people out there struggling and suffering,” Howard said, “and being a minority-owned business, you know, we feel a responsibility to shed a good light on our community.”It’s all just one part of their unusual recipe for success. 2175

Police said four people were injured Wednesday in two separate knife attacks about 30 minutes apart in central Vienna, Austria.Three victims were injured in the first attack outside a restaurant near the Nestroyplatz subway station, a police spokesman told CNN. The victims were a couple and their daughter, CNN affiliate ORF reported.The fourth victim was injured in the second attack at Praterstern, a major city square, the spokesman said.Authorities are investigating whether the incidents are linked, the spokesman said.Police are still searching for the attacker or attackers, the spokesman said.Witnesses said they saw police swarming the area.Michael Eisenriegler, who lives next to where the stabbing happened, told CNN he saw flashing lights and went downstairs."There were maybe ... one or two dozen policemen (at the site of the attack.) And they are still there," he said."(The road) is blocked. They are searching," Eisenriegler said.Clemens Oistric, a journalist at Austrian newspaper Heute, said he was in his office nearby during the attack."People shouted because three people were hit by a man who had a knife. They're in hospital," Oistric said told CNN. 1182

Police in tense downtown Portland on Saturday ordered protesters to disperse and leave a location where they saw people throwing projectiles, including rocks and bottles."Failure to comply with this order may subject you to arrest or citation, and may subject you to the use of riot control agents or impact weapons," police said on Twitter and on a loudspeaker at the scene.This came as dueling political rallies took place and police braced for potential violence. They told people not to bring weapons and warned that checkpoints and bomb-sniffing dogs would be on hand.Members of law enforcement -- who wore heavy armor on the streets -- ran toward protesters and continued to move them farther away from the location where flash-bang grenades were deployed, a CNN affiliate live signal from the ground shows."We aren't here to fight the police," a protester yelled. "We're here to fight the Trump supporters." 922

PANMUNJOM, Korea (AP) — With wide grins and a historic handshake, President Donald Trump and North Korea's Kim Jong Un met at the heavily fortified Demilitarized Zone on Sunday and agreed to revive talks on the pariah nation's nuclear program. Trump, pressing his bid for a legacy-defining deal, became the first sitting American leader to step into North Korea.What was intended to be an impromptu exchange of pleasantries turned into a 50-minute meeting, another historic first in the yearlong rapprochement between the two technically warring nations. It marked a return to face-to-face contact between the leaders after talks broke down during a summit in Vietnam in February. Significant doubts remain, though, about the future of the negotiations and the North's willingness to give up its stockpile of nuclear weapons .The border encounter was a made-for television moment. The men strode toward one another from opposite sides of the Joint Security Area and shook hands over the raised patch of concrete at the Military Demarcation Line as cameras clicked and photographers jostled to capture the scene.After asking if Kim wanted him to cross, Trump took 10 steps into the North with Kim at his side, then escorted Kim back to the South for talks at Freedom House, where they agreed to revive the stalled negotiations.The spectacle marked the latest milestone in two years of roller-coaster diplomacy between the two nations. Personal taunts of "Little Rocket Man" (by Trump) and "mentally deranged U.S. dotard" (by Kim) and threats to destroy one other have given way to on-again, off-again talks, professions of love and flowery letters."I was proud to step over the line," Trump told Kim as they met in on the South Korean side of the truce village of Panmunjom. "It is a great day for the world."Kim hailed the moment, saying of Trump, "I believe this is an expression of his willingness to eliminate all the unfortunate past and open a new future." Kim added that he was "surprised" when Trump issued an unorthodox meeting invitation by tweet on Saturday.As he left South Korea on his flight to Washington, Trump tweeted that he had "a wonderful meeting" with Kim. "Stood on the soil of North Korea, an important statement for all, and a great honor!"Trump had predicted the two would greet one another for about "two minutes," but they ended up spending more than an hour together. The president was joined in the Freedom House conversation with Kim by his daughter and son-in-law, Ivanka Trump and Jared Kushner, both senior White House advisers.Substantive talks between the countries had largely broken down after the last Trump-Kim summit in Hanoi, which ended early when the leaders hit an impasse.The North has balked at Trump's insistence that it give up its weapons before it sees relief from crushing international sanctions. The U.S. has said the North must submit to "complete, verifiable and irreversible denuclearization" before sanctions are lifted.As he announced the resumptions of talks, Trump told reporters "we're not looking for speed. We're looking to get it right."He added that economic sanctions on the North would remain. But he seemed to move off the administration's previous rejection of scaling back sanctions in return for piecemeal North Korean concessions, saying, "At some point during the negotiation things can happen."Peering into North Korea from atop Observation Post Ouellette, Trump told reporters before he greeted Kim that there had been "tremendous" improvement since his first meeting with the North's leader in Singapore last year.Trump claimed the situation used to be marked by "tremendous danger" but "after our first summit, all of the danger went away."But the North has yet to provide an accounting of its nuclear stockpile, let alone begin the process of dismantling its arsenal.The latest meeting, with the U.S. president coming to Kim, represented a striking acknowledgement by Trump of the authoritarian Kim's legitimacy over a nation with an abysmal human rights record. Kim is suspected of having ordered the killing of his half brother through a plot using a nerve agent at a Malaysian airport in 2017. Meantime, the United Nations said in May that about 10 million people in North Korea are suffering from "severe food shortages" after the North had one of the worst harvests in a decade.Trump told reporters he invited the North Korean leader to the United States, and potentially even to the White House."I would invite him right now," Trump said, standing next to Kim. Speaking through a translator, Kim responded that it would be an "honor" to invite Trump to the North Korean capital of Pyongyang "at the right time."Trump became the first sitting U.S. president to meet with the leader of the isolated nation last year when they signed an agreement in Singapore to bring the North toward denuclearization.In the midst of the DMZ gathering, Trump repeatedly complained that he was not receiving more praise for de-escalating tensions on the Korean Peninsula through his personal diplomacy with Kim. Critics say Trump had actually inflamed tensions with his threats to rain "fire and fury" on North Korea, before embracing a diplomatic approach.North Korea's nuclear threat has not been contained, according to Richard Haas, president of the New York-based Council on Foreign Relations. He tweeted Sunday that the threat of conflict has subsided only because the Trump administration has decided it can live with North Korea's "nuclear program while it pursues the chimera of denuclearization."Every president since Ronald Reagan has visited the 1953 armistice line, except for George H.W. Bush, who visited when he was vice president. The show of bravado and support for South Korea, one of America's closest military allies, has evolved over the years to include binoculars and bomber jackets.While North Korea has not recently tested a long-range missile that could reach the U.S., last month it fired off a series of short-range missiles . Trump has brushed off the significance of those tests, even as his own national security adviser, John Bolton, has said they violated U.N. Security Council resolutions.___Associated Press writers Jill Colvin and Darlene Superville in Washington contributed to this report. 6301
