"Baltass," the Ultimate Cups-and-Balls Illusion

Original image
YouTube

Yann Frisch is a French sleight-of-hand artist best known for a routine called Baltass (a portmanteaux of the French words for "ball" and "cup," balle and tasse), in which he elevates the old cups-and-balls trick into a serious art form. This is true performance art -- aside from the astonishing dexterity required to perform this routine, it evokes surprise, laughter, and even empathy for the frustrated conjurer. In the routine, Frisch's character seems simultaneously dejected that he can't rid himself of the balls, but also curious to see where they keep coming from. It's funny, weird, and very French.

If you enjoy magic, art, or just having your mind blown, watch this performance of Baltass from the 2012 Beijing International Magic Convention:

For more context on the cups-and-balls routine, enjoy this six-minute history lesson/sleight-of-hand demo from Ricky Jay:

If that's still not enough, enjoy Frisch experimenting with a poker chip.

How IKEA Turned the Poäng Chair Into a Classic
Original image
Ikea

IKEA's Poäng chair looks as modern today as it did when it debuted in 1976. The U-shaped lounger has clean lines and a simple structure, and often evokes comparisons to Finnish designer Aalto’s famous “armchair 406.” Its design, however, is ultimately a true fusion of East and West, according to Co.Design.

In 2016, the Poäng celebrated its 40th birthday, and IKEA USA commemorated the occasion (and the 30 million-plus Poäng chairs they’ve sold over the years) by releasing two short videos about the armchair’s history and underlying design philosophy. Together, they tell the story of a fateful collaboration between Lars Engman, a young IKEA designer, and his co-worker, Noboru Nakamura.

Nakamura had initially come to IKEA to learn more about Scandinavian furniture. But the Japanese designer ended up imbuing the Poäng—which was initially called Poem—with his own distinct philosophy. He wanted to create a chair that swung “in an elegant way, which triggered me to imagine Poäng,” Nakamura recalled in a video interview. “That’s how I came up with a rocking chair.”

“A chair shouldn’t be a tool that binds and holds the sitter,” Nakamura explained. “It should rather be a tool that provides us with an emotional richness and creates an image where we let go of stress or frustration by swinging. Such movement in itself has meaning and value.”

Save for upholstery swaps, a 1992 name change, and a new-ish all-wooden frame that's easily flat-packed, the modern-day Poäng is still essentially the same product that customers have purchased and enjoyed for decades. Devotees of the chair can hear the full story by watching IKEA’s videos below—ideally, while swinging away at their desks.

Why Haven't We Cured Cancer Yet?

Walkathons, fundraisers, and ribbon-shaped bumper stickers raise research dollars and boost spirits, but cancer—the dreaded disease that affects more than 14 million people and their families at any given time—still remains bereft of a cure.

Why? For starters, cancer isn't just one disease—it's more than 100 of them, with different causes. This makes it impossible to treat each one using a one-size-fits-all method. Secondly, scientists use lab-grown cell lines cultivated from human tumors to develop cancer therapies. Living masses are far more complex, so potential treatments that show promise in lab experiments often don't work on cancer patients. As for the tumors themselves, they're prone to tiny genetic mutations, so just one growth might contain multiple types of cancer cells, and even unique sub-clones of tumors. These distinct entities might not respond the same way, or at all, to the same drug.

These are just a few of the challenges that cancer researchers face—but the good news is that they're working to beat all of them, as this TED-Ed video explains below.
