How Giant Tesla Coils Work

Giant Tesla Coils can do some neat stuff with huge zaps of power. For instance, here's the band ArcAttack performing the Legend of Zelda theme mashed up with "SexyBack":

(More like that.)

So...how does that work? In this 15-minute video, Norm from Tested gets technical with ArcAttack on exactly how their coils are built, how they make music with them, and how much juice is involved. If you have even the slightest interest in building giant Tesla Coils, prepare to get nerdy.

My favorite line: "They're loud, and they kind of sound like heavily distorted trumpets...which is a very odd instrument to have to write music for."

Weird
U2’s 360-Degree Tour Stage Will Become a Utah Aquarium Attraction

The immense stage that accompanied U2 on the band’s 360° Tour from 2009 to 2011 is getting an unexpected second life as a Utah educational attraction. It will soon be installed over a new plaza at the Loveland Living Planet Aquarium outside Salt Lake City.

The Claw, a 165-foot-tall structure shaped like a large spaceship balanced on four legs—a design inspired by the space-age Theme Building at Los Angeles International Airport—was built to house a massive speaker system and cylindrical video screen for the band’s performances. Underneath it, a 360° stage allowed U2 to play to audiences surrounding the structure in all directions. To make it easier to tour 30 different countries with the elaborate system, which took more than a week to put together at each concert location, the band had several versions built.

U2 and its management have been looking for a buyer for the 190-ton structures since the tour ended in 2011, and it seems they have finally found a home for one of them. One of the two remaining Claw structures is coming to the Utah aquarium, where it’s being installed as part of a plaza at the institution’s new, 9-acre Science Learning Campus.

As the only Claw in the U.S., the alien-looking feat of engineering will be "preserved and sustainably repurposed as a Utah landmark and symbol of science exploration and learning," according to the aquarium's press release. As part of the expansion project, the 2300-square-foot stage system will play host to festivals, movies, and other special events in two venues, one with 7000 seats and the other with 350.

The $25 million Science Learning Campus hasn’t been built yet—construction is starting this fall—so you’ll have to wait awhile to relive your U2 concert experience at the aquarium.

This Beatles Poster Breaks Down the Instruments Played in Every Fab Four Song

If you're a Beatles fan who has memorized every second of every one of the legendary band's songs, from instruments to vocals, Pop Chart Lab has got a poster for you.

"Come Together," the pop culture-loving design company's latest poster, breaks down the instruments featured in every single one of The Beatles's songs, from 1963's "I Saw Her Standing There" to 1970's "Get Back." The chart is broken down into five colors—one for each member of the Fab Four, plus one hue to represent various non-band members—and the icons show you which instrument each member plays in each tune, from the conventional (guitar) to the unique (tape loops and mellotrons). Grab your headphones and follow along as you listen: soon you'll be able to impress your friends by rattling off who's singing when. Who knows—it might even inspire you to pick up the guitar and learn "Blackbird."

The poster measures 24 by 36 inches and pricing starts at $37. It's available for preorder now, and shipping begins April 20.

Music fans will also love Pop Chart Lab's other music posters, like this spread of famous guitars or this brilliant taxonomy of rap names.
