The answer is differential expansion, as Martyn Poliakoff explains below. The outside of the ice cube is warmed by the drink and expands, but the inside remains cold. The stresses thus introduced cracks the cube.
Interestingly, you can make this happen the opposite way, as well. Drop some ice into liquid nitrogen, and the outside is cooled and shrinks, while the inside stays warm, leading to a similar fracture effect.

On Tuesday morning, an Indonesian Hercules C-130 military transport plane crashed into a busy Medan neighborhood, just minutes after takeoff. At least 30 people died in the crash, Indonesian search-and-rescue official Hisar Turnip tells Reuters. "That's the latest information, the number could go up."

The plane, built in 1964 and carrying 12 people, circled over the neighborhood three times before crashing into a hotel and massage parlor, a hotel employee told Reuters. Medan, on the island of Sumatra, is Indonesia's third-largest city. You can see the immediate aftermath of the crash in the video below. Peter Weber
No Supreme Court member was more distraught and dismissive of the court's ruling that gay couples have a constitutional right to civil marriage than Justice Antonin Scalia. On Monday's Daily Show, Jon Stewart laughed at the highlights of Scalia's blistering dissent — "jiggery-pokery," "pure applesauce" — but then noted the more troublesome parts, where Scalia suggests the court subverts democracy and the Constitution.
Scalia, it turns out, has had no qualms about subverting democracy and the separation of powers when it suits his needs, Stewart noted, with examples. But Scalia was obviously very upset by the ruling, and Stewart decided to cheer him up by trolling him. "I feel bad for Scalia, I really do," Stewart said, calling the justice a "modern-day Diogenes" and presenting him with a "gesture of empathy" — an animated short called "Antonin Scalia and the Horrible, Terrible, No Good, Very Bad Day."

This summer, starting on its Los Angeles to San Francisco route, United Airlines will fly commercial jets using a biofuel made out of plant oil and animal fat. In 2013, United agreed to buy 15 million gallons of the fuel, produced in California by AltAir Fuels, over three years, with the option to buy more. AltAir uses discarded farm waste like tallow (rendered animal fat) plus non-edible natural oils to make biofuel that works in existing jet engines.
The AltAir fuel will be blended with traditional jet fuel, starting with a 30/70 mix. But United isn't placing all its bets on AltAir. On Tuesday, The New York Times says, United will announce a $30 million investment in Fulcrum BioEnergy — a small amount compared with the $11.6 billion United spent on fuel last year, but the largest such investment by a U.S. carrier to date. Fulcrum turns municipal garbage into aviation fuel, promising cheap green fuel from a plentiful source of raw material.
Airlines are trying to reduce their carbon emissions but alternative, sustainable sources of jet fuel aren't yet available in dependable quantities. The industry hopes to cut its greenhouse gas emissions to half their 2005 levels by 2050. Peter Weber
A strange real estate saga is unfolding in Los Angeles, featuring a restaurateur and nightlife doyenne, six nuns, and Katy Perry.
The Sisters of the Most Holy and Immaculate Heart of the Blessed Virgin Mary purchased an 8-acre property in Los Feliz in 1972, and now that they all live in retirement homes, they want to sell the convent and live off of the proceeds. The nuns closed a deal with restaurant owner Dana Hollister for $15.5 million, but the Archdiocese of Los Angeles said they acted too quickly, and it's not actually their property to sell. Sister Catherine Rose, 86, disagrees. "We have control of our property, it's ours," she told ABC Los Angeles. "The archdiocese is not taking care of us, we've been taking care of ourselves."
The archdiocese claims the Immaculate Heart of Mary Institute is ultimately governed by the Holy See, and is trying to void the sale and evict Hollister. This is the part where Perry comes in — the archdiocese claims the singer has offered a better deal that will be more beneficial to the nuns. Sister Catherine Rose said all of the nuns met with Perry, but aren't fans of her songs and don't want to see her turning the convent into Our Lady of the Whipped Cream Shooting Bras. "She answered nicely but her answers were not what we were looking for," Sister Catherine Rose said. The first hearing in the civil suit will take place July 9. Catherine Garcia
More than a month after the World Health Organization declared Liberia free of Ebola, the corpse of a 17-year-old tested positive for the virus.
WHO made the announcement after 42 days passed without a case of Ebola being reported. Since the teen's death on June 24, no other cases have been reported, Tolbert Nyenswah, the country's deputy health minister and head of the Ebola response team, told The Associated Press. "We have said over and over again there was possibility that there could be a resurgence of the virus in Liberia," Nyenswah said. "But our surveillance teams, our capacity is very strong."
Liberia was hit hard by the outbreak that started in 2014, and more than 11,100 people have died from Ebola in West Africa since last year. Officials are not sure how the young man contracted Ebola; the virus is still in Guinea and Sierra Leone, but he did not live close to those borders. Nyenswah said officials are looking into his recent travel, and added that residents of the teenager’s town, 30 miles south of Monrovia, have nothing to worry about. "There is no need for pandemonium," he said. "People should go about their normal business." Catherine Garcia
"Last week was amazing," Jon Stewart said on Monday's Daily Show, pointing to the Supreme Court decisions on ObamaCare, fair housing, and, especially, same-sex marriage. But of course, prominent national Republicans weren't pleased with the gay marriage decision, and Stewart played a few of the more vocal dissents, gleefully shooting them down as soon as they were raised. Then he got to the bottom line.
"Look, justices, senators, your problem isn't judicial activism, or overreach, or politically correct policing," Stewart said. "Your problem here is bald-faced, out-in-the-open, common sense experience. That's why you're not going to win the marriage-equality fight." To illustrate his point, he showed a clip of Donald Trump acknowledging that his three marriages aren't very traditional. "You're not going to win the marriage-equality fight because even a man pathologically disposed to not understand other people's points of views," he said, pointing at Trump, "even he gets it."

A man died on Tuesday after setting himself on fire while riding a bullet train from Tokyo.
Another passenger on the train went into cardiac arrest, Reuters reports, and two others were seriously injured. The man is believed to have been in his 30s, and was found covered in a flammable liquid, officials said. The train was headed to Osaka with 1,000 passengers when someone hit the emergency button and the passenger was discovered. Local media is airing footage showing passengers streaming out of a train carriage filled with smoke. Catherine Garcia
