Watch 11,000 Marbles Run Wild

Some people build model trains. Some people play video games. Jelle Bakker, known as The Marble Master, builds super-complex Rube Goldberg machines for his tens of thousands of marbles to run through. It's good to have a hobby.

In this video, we see the Marble Tsunami, a giant contraption through which 11,000 marbles flow. As they roll along, the marbles set off chimes, hit bells and bumpers (like in a pinball game), go around loops, tip trays, and do other rather impressive mechanical things. The most incredible aspect is the sound of these things clattering; when installed, Bakker promises sound-dampening material to protect viewers' ears. (This thing is going on display this month at the Gouda Monkey Town Indoor Playground in The Netherlands.) For now, just turn down the sound.

Prepare to lose your marbles.

Fun fact: This kind of machine is called a "knikkerbaan," which roughly translates to "marble lane." (Thank you, reader Miranda Kate!)

Hate Red M&M's? You Need a Candy Color-Sorting Machine

You don’t have to be a demanding rock star to live a life without brown M&M's or purple Skittles—all you need is some engineering know-how and a little bit of free time.

Mechanical engineering student Willem Pennings created a machine that can take small pieces of candy—like M&M's, Skittles, Reese’s Pieces, etc.—and sort them by color into individual piles. All Pennings needs to do is pour the candy into the top funnel; from there, the machine separates the candy—around two pieces per second—and dispenses all of it into smaller bowls at the bottom designated for each variety.

The color identification is performed with an RGB sensor that takes “optical measurements” of candy pieces of equal dimensions. There are limitations, though, as Pennings revealed in a Reddit Q&A: “I wouldn't be able to use this machine for peanut M&M's, since the sizes vary so much.”

The entire building process lasted from May through December 2016, and included the actual conceptualization, 3D printing (which was outsourced), and construction. The entire project was detailed on Pennings’s website and Reddit's DIY page.

With all of the motors, circuitry, and hardware that went into it, Pennings’s machine is likely too ambitious of a task for the average candy aficionado. So until a machine like this hits the open market, you're probably stuck buying bags of single-colored M&M’s in bulk online or sorting all of the candy out yourself the old fashioned way.

To see Pennings’s machine in action, check out the video below:

Watch 18 Minutes of Julia Louis-Dreyfus Seinfeld Bloopers

Sometimes you just need to settle in and watch professional actors cracking up, over and over. That's what we have for you today.

In the two videos below, we get a total of 18 minutes of Seinfeld bloopers, specifically focused on Julia Louis-Dreyfus. When Louis-Dreyfus cracks up, Seinfeld can't help but make it worse, goading her. It's delightful.

Sample quote (during an extended break):

Seinfeld: "We won an Emmy, you know."

Louis-Dreyfus: "Yeah, but I didn't."

Her individual Seinfeld Emmy arrived in 1996; the show started winning in 1992. But in September 2017, Louis-Dreyfus—who turns 57 years old today—set a couple of Emmy records when she won her sixth award for playing Selina Meyer on Veep.
