I figured out that making the cartoon Transformers noise when the magnets start moving adds to the fun, FYI

fuckin magnets


Hope dude was wearing safety glasses, I saw some shrapnel flying away in a few of those clips. Neodymium magnets are really brittle!

Oh, but some of these appear to defy the conservation of momentum in the most pleasing of ways.

Cool! Now I want a ultra slow motion camera to film stuff like this!

I noticed the light slowly flickering in intensity in most of the clips; I wonder if that was the background lights flickering at 50 or 60 hz, depending on the filming location.

Those who love this kind of stuff probably need to have a look at Magnet Expert's channel. This may be the only place where you can see what it likes to see Super-strong neodymium magnet pair take on a hamburger in slow motion. And if you like the idea of getting your own one of those - then Brian will talk you through some tips on how not to take off your hand. One day you might have a MONSTER.

I squealed with joy.

And, weirdly, I now want nothing more than to get a bunch of dancers together to recreate the exact, inevitable, weighty, random finality of this movement. They'd need to bravery of Pilobus and the precision of the Rockettes, but I bet it would be incredible.

I actually have a camera that will record at 1000fps. Clearly I need to get onto some of this.

Great share, rongorongo. That monster magnet... $1230 for that thing! That dude is committed to his craft!

warning: "monster takes on blood" isn't some kind of confusing metaphor. It involves a significant amount of literal blood.

Whenever the ball magnet is not on screen, all the other magnets should be asking, "Where's the ball magnet?"

This unboxing video reminds you to remove all metal items including 'pacemaker'

In case anyone is curious, magnets are used to put pacemakers in a mode where they put out a steady 70 pulses per minute regardless of what the patient is doing. This is useful for testing the battery (as it nears the end of its life the rate will decrease below 70) or when in situation where the pacemaker may be exposed to electrical interference, as with electrosurgery units in the operating room. In theory, removing the magnet will return the pacemaker to its original programming, but with a magnet this strong it would be prudent to have it interrogated by a technician, just to be sure.

Am I the only one who's afraid of using that near other things, out of serious concern for making everything it touches magnetic?

Why yes, I do want to see that! I feel like they are saying, "I love you I love you I love you I love you!" when they collide like that.

Hey now, what kind of backend tomfoolery is that post title/link address?

So, funny little detail of posts and moderation: we generate the stub text at the end of the URL of a post automatically based on the content of the title of the post. This works fine like 99% of the time; you hit post on your new post, the server throws the title through a cleanup filter, and it sticks the resulting output in the stub field.

But to avoid various kinds of trouble for web browers etc, url stubs need to not contain problem-causing characters, which includes things like most punctuation and all emoji. We play it real safe, probably more so than is strictly technically necessary, and just strip out anything that isn't basically straight ASCII.

But if a title consists of pretty much ONLY emoji or punctation, the resulting stripped stub can end up being very short or outright blank. This doesn't cause problems by itself, so if a stub ends up being empty it's okay, but it's better for e.g. search engine preferences if the url has some additional semantic content, and so for titles with very short or entirely blank stubs we have the server generate an email alert saying "no stub on post xxxxxx". I see that, I go into the post edit form, and I toss in something descriptive and on-topic.

But I realized as I was posting this that I was gonna get no stub on my own post, so I just immediately edited it after posting to toss "oooppppppooosssiiittteeesss-aaattttttrrraaacccttt" in because hey, fuck it, I work here.

If you look at posts with emoji-heavy titles, you may see the same thing going on (Fizz has had a couple recently for example), but I tend to take less aesthetic license with other folks' posts.

Neat to watch the string of buckyballs just disintegrate as it approaches the big block magnet.

Oh. I was thinking maybe it would rip the pacemaker out of your chest, but that's cool too.

Oh God his hands are all scratched up from playing with those powerful magnets. I really appreciate all those videos so much more now.

I had to have a MRI scan recently and the safety checks were pretty extensive... I had to go through a long check list on several occasions - when it was booked, when I received my appointment, on the day - to make sure there was nothing potentially magnetic in my body or that could be disrupted by magnetic fields / radio waves like pace makers, stents etc. They even warned me about tattoos possibly having metallic inks... I don't think there's a danger of them being ripped from your living flesh, but if they start getting hot you are supposed to ask them to stop the scan.
