Creative. I knew you had magnets in the ends. I just didn’t know the method of concealment.
Pretty close to what I had guessed, although I thought you had used mild steel inserts that really could be magnetized and demagnetized instead of rare earth magnets. Masterfully done, Joe!
Thanks.
I suspected the hidden neo magnet. Nice machining. Hope someone doesn't mistake it for an aluminum slug.
This was one of my favourite gags I saw for this years April Fools, thanks for sharing the behind the scenes look.
Excellent April fools prank....I must admit you had me for a few minutes....scratched the hair right off my head! Lol. Thanks Joe!
Dang it, now that you revealed it, my aluminum note holder will probably fall off my refigerator now!
Thanks, always look forward to your April Fools Tom Foolery!
“Leave a thumbs up if you enjoyed the video.” me: I have enjoyed every video I have watched. A fantastic light hearted video. Thanks Joe.
I called it April 1st. Still nice to see you take the time to have some fun!
Joe, if you drop a strong magnet into a piece of aluminum tubing several feet (~1-m) long, the magnet's magnetic fields will interact with the aluminum enough to slow its fall. To demonstrate, drop a piece of demagnetized steel (or similar) through the vertical tube & note how about how long it takes to fall through the tube. Then drop the magnet into the vertical tube and note how much slower its fall through the tube is. I think that's what you were thinking of near the beginning of this video.
You mentioned about Aluminium "reacting to a magnetic field possibly" Yes it can and its a favourite trick of mine around the workshop. All you have to do is drop a magnet through an Aluminium tube (This is more commonly done with copper tube) and the magnet will pass through it a lot slower than you would expect.
Two great videos Joe. Both very well presented, gave me a good chuckle too
I enjoy your April 1st videos. You have an audience that knows you are spoofing something, but the objective is to figure out how it was done.
Keeps it interesting. :)
@@joepie221 Keep the mind moving and the body will follow,
The reveal is as nice as the hoax. Well done again.
You crafty fellow, you. Good job. The parting pip really sold it, I gotta say.
GeoD
You're correct that aluminium can interact with a magnet.
It's the effect of Lenz's law.
this was brilliant! I knew about the Eddie current in Aluminium, but your trick was perfect! (and believable) I am sure a lot of the viewers fell for it.
I look forward to these videos every April 1st, please keep up the tradition :D
I'll certainly try.
FYI An Eddy current field electromagnetism will repel an aluminum parts ,, Common use in recycle sorting conveyor head pulleys to toss aluminum cans and let plastic items fall free !!
That was good prank 👍a lot of effort and planning. Nicely done Joe !
Yes it was. Thanks.
Joe, you are wonderful......best wishes from Florida, Paul
Thanks Paul. Back at ya.
Joe, your video did start dialog over this topic with a buddy.
U-tube Video by sparkstarter " Electromagnet for Attracting Copper, Aluminum and Non-Ferrous Metals like GOLD! "
This guy uses an electrical magnet supply to induce eddy currents in a thin piece of Aluminum foil to make it actually move.
Reference Book by Leonard R. Crow (1950's)
"Design, Construction and Operating Principles of Electromagnets for Attracting Copper, Aluminum , and Other Non-Ferrous Metals"
Sparkstarter has a link to a clip of book in pdf. Funny part is my buddy has a hard copy of this old book on his shelf.
I love these style of April fools jokes
I was thinking to plug the end with aluminum slug rather than capping, however it was executed it with the same result.. cheers!
Love it! Very nice job!
Always a lot of knowledge on your channel..... Thanks Joe!
awesome! Please teach us how to mill some loaded dice 🎲 next (for pranks only) haha
Hey Joe I gotta great laugh out of this April fools joke when it went to air on your video, my trade school teacher did exactly the same thing to me when I was an Apprentice. Mind you back then we could figure out how he concealed the magnet in the Alloy tube until he showed us brought back great memories and a laugh. Thanks Joe. Australia.
It was good he let you off the hook.
As Joe often does, a simple solution to a seemingly difficult problem, performed with machining skill.
Thanks for that Jo. It made me smile 😊
Only time I remember April Fool Day is when Joe does something like this!!! Then I can't wait to see hoe he ACTUALLY did it, compared to what I thought he did.
This time I was pretty close. Can't wait for next year. Thanks Joe--All the best from Australia
Thanks. Stay well.
Nicely done Joe. I just recalibrated a mechanical speedo and the rotating magnets do draw an aluminium cup around to move the needle. So aluminium does react to a moving magnetic field. I'm no expert but I think eddy currents have something to do with it. Could be completely wrong on that last bit. I showed it in some videos. All the best, Mart in England.
Here is the stupid question. First off I am not a machinist. Secondly I am not a machinist. I do have a south bend heavy 10 and a 747 wells index but again this is just a hobby for me. The magnets work great but, Could you bore and ream to fit a long piece of steel? This way you are actually magnetizing the steel over the magnetizer inside but the outside is still aluminum??????….IS IT POSSIBLE??? Thanks again JOE.. Your videos always amaze me. I watched the heart video and made one for my wife. You are truly talented……
It was a demagnetizer that he has, remember he said he modified it to be a magnetizer, as part of the joke.
Yes but the steel would need to be hardened to retain the magnetism. The way he did it is much easier.
You made an excellent spoof Joe :)
Thanks.
Well done! Love it!
i just assumed you pressed a piece of steel in there and that the magnetization step was real.
Mr . Pie cool trick !
I was pretty close with my guess, except instead of your elaborate cap I was thinking it was bored, magnet inserted, and a piece of aluminum with the OD of the bore was pressed in. I like your way better though.
Aluminum rods would make for great refrigerator magnets. I will have to make some and see if anyone notices.
Nice and good to heat MR. Kompressor is back in Buissnes
He knows just when to get in the picture.
Very cool April Fools! Aways enjoy your videos
I thought it was strange but I didn’t notice the date. You got me! A very good April fool joke. 😂
Nicely sneaky. Good job indeed.
Well thought out !Thanks for the looksee.
No problem 👍
Make a playlist of your April fool shows😊
There is only 2 so far with 2 reveal videos. I may do that. Thanks for the suggestion.
@@joepie221 just make them easy to find for the subscribers of the future
My kids were watching the video from before and were both trying to figure out what was going on. Good times.
I knew aluminium is not magnetic but this is Joe Pie we are talking about and for a bit I did wonder??? 🤣❤️🇬🇧 p.s and yes that’s how it should be spelled.
Always interesting to see your inventiveness for April Fools Day... Now, I'm ready for more miniature milling machine.... Keep'um Coming....!
Well played!! Thanks Joe! ; -)
Love it! I got to make a couple to have fun with the grand kids and family. Lol. Thanks for sharing, Ken
Well done, as always I love your content
Actually the cutoff nipple to me was a "trick too far". My immediate thought was that was done on purpose. I don't think I've ever seen you leave a cutoff nipple on anything.
Some of my left over bar ends have them, but never on a finished part. NOBODY even caught the message on the original video description either. Its there, ya just have to think outside the box to see it.
Aluminium DEFINITELY reacts to a changing magnetic field: that induces huge eddie currents.
In 8 years we learn that Joe passed from finger cancer from a faulty "de-magnetizer" and being a prankster one April fools day.
Boy I hope not. :(
Hey Joe, Way to go brother. CRAZY JOE Thank you sir
By this we will redraw your nomination for the Nobel-price.
Thank you for your April Fools’ Day joke, but when I saw it, I knew it was a joke because last year you did a similar thing
Pretty much what l figured was done.
Now do transparent aluminum!

I did enjoy the original. Clearly something clever was done but it's nice to see the actual details. And I did see the rod after the degausser go out of frame for that blink of an eye and thought "AH HA!"....
Any conductor can react with a magnetic field. The trick with dropping a magnet down a piece of copper pipe works with other metals too. And that includes aluminium. Just not as well due to other metals having a slight to some additional electrical resistance.
WHAT !?!?! It was fake ??!? Noooooooo !!!!!!! I thought for sure this was going to finally lead to those flying cars that Popular Mechanics promised me would be in my driveway within 10 years.....back in 1965. ;)
Great trick and it looks like you had a lot of fun making it.
Your too good 😂
Thanks. It was fun.
Hahaha! I just chalked it up as, if it can be done Joe Pie can do it.
Not like I’ve been magnafluxing for 30 years or anything like that.
Like I said, next year lets see a Harley that defies gravity and floats in the air. That one might start a few bar fights 🙂
I'm sure someone fell for your april fools day joke. Good one.
I suspected that it had iron core(s). Aluminum is paramagnetic. It has a VERY small attraction to magnets but cannot be magnetized. Below 2 Kelvin it is a superconductor: An aluminum ring will support persistent supercurrents as long as it is kept cold and this structure acts like a magnet. All conductors are repelled by an oscillating magnetic field due to the 'eddy currents' induced in them by the changing field.
You did have to work for that joke. Well done, good joke.
It did require some prep and shot planning to pull it off. Thanks for checking in.
Good job (as always)
Thanks.
Thanks for sharing 👍 A good one 😅
Yes, you can get a force from a magnet on aluminum. If you run it past a strong magnet, you'll get a braking effect from the induced current. Dropping a cylindrical Nd magnet down a piece of copper tube is a good demo of the effect.
I liked my variation a bit better, since it wouldn't have required a swap. FWIW, i doubt that demagnetizer is anywhere here powerful enough to degauss a Nd magnet.
I think the reason to use plain stock was to prevent obvious interaction with magnetic field. Then again he could have just modified the power switch :-)
What determines if a metal/material is magnetic is the orbital spin. Usually its the D orbital
You can make non metalic elements magnetic with things like liquid nitrogen.
Aluminum does get reluctance if you move a strong magnet close to it. Example: Dropping a magnet through an aluminum coil will slow it down to a crawl.
that's not a chemical property though but a purely physical property that comes from the conductivity
I was thinking you stuffed the bar with steel the magnetized it but inserting magnets is easier. Any conductive material can become temporarily magnetized if subjected to a moving/changing magnetic field by causing eddy currents inside the conductor. That's how magnet dampened systems like balance scales work..
Dampening isn't the same as a static magnetic field though. The magnetic field from eddy currents only exists as long as there's relative movement. It also needs an external magnetic field since aluminium can't be magnetic by itself
@@CatNolara That's what I wrote. The magnetic field had to be moving relative to the material.
@@maxheadflow either moving or changing in other ways, like by high frequency current in an induction heater. Also, I wouldn't call the material being "magnetized", I think that only includes materials that keep a permanent magnetic field after being exposed to a strong enough magnetic field.
@@CatNolara Ok how about temporally magnetic. It has to create magnetic force (counter) to dampen the movement. I was trying to keep things simple. 😁
Very clever.
your too good
I knew it from the start.
But it was still a great trick.
Yeah, you got me for a bit. Great stuff!!
Glad you enjoyed it!
Joe you say that aluminium is not magnetic, I dissagree as the speed indicator on your DoAll bandsaw is an aluminium disc with the pointer on with a rotating magnet driven by a belt off the gearbox. There is sufficient magnetic flux to pull the disc around to indicate the speed. Also too an electricity meter at your house uses an aluminium disc and a coil, as current passes through the coil it atracts the aluminiun disc which rotates. On the end of the shaft is a gear which drives the numbers round to show how much electricity has been used. Regards from Australia.
Aluminium that is subject to a changing magnetic field will have electricity induced in it. Electrical flow creates magnetism. This is the principle on which AC motors works. Is the aluminium magnetic? Debatable as it requires a changing magnetic field. Personally I'd argue it is not.
Wouldn't that make the aluminum capable of being influenced by a magnetic field as opposed to actually being magnetic?
The argument that could be made is that as electricity moves through it it behaves as a magnet. It will never be a natural magnet but in that split second it repels and attracts magnetic poles... what is a magnet?
Lenz's law is that the induced electricity in the aluminium and the subsequent magnetic field that this induced current causes in such discs will oppose the cause so I suspect the coil will be pushing the disc around rather than pulling it.
I admit it, I was tricked. But then entertained. Thank you.
Glad you enjoyed it
Thanks again
If you want to see how to actually lift aluminum with electromagnets check out Lenz's law.
Next year make a bar of iron that can't hold magnetism. ;)
when I worked at the local iron works as a sparks I was called out to the pig casting plant the OHC magnet would not pick up the pig iron , so quick check for power and amps 220 vdc and 60amp was ok , it was not until I was standing near it when it was on and and my steel toe cap boot stuck to it I knew it was ok . end result was the pigs all 75 ton had to be hand/ machine loaded , and the iron was tested and found to be if memory was correct to much silicone but hey that was 60 years ago so it can be done
That was fun😊
Proper magician techniques, very nice. Many of the best illusions are a combination of sleight of hand and highly engineered accessories. If this machinist thing doesn't pan out, there's always the stage.
😂
True. I not sure I want to be a machinist when I grow up.
good video mr joe pie
Glad you enjoyed!
I like it !!!
Is that an AC demagnetizer? Put an aluminum plate on top and turn the power on. Magnetic tape in aluminum reels does fun stuff on the eraser at 60 hertz.
you had me!!
It looked believable.
As the old saying goes,” don’t believe any of what you hear and only half of what you see”. Nice joke.
Another good one 👍! 😂
Nice one.
Love it
Great trick
👍i thought my degaussing tool was bad. I can stop trying now.😅
Mystery solved.
A great gag! Do you remember hearing about transparent aluminum ? Looks like the sun is a lot stronger down where you are. Thanks, as always. Can’t wait until next year. Start thinking about it.
There is real transparent alum, which is fun to find out lol
@@XXCoder Transparent aluminum was in a Star Trek movie, when they transported a whale.
@@greglaroche1753 I know.
For even more fun ya could finish the Honda engine.
No kidding. Getting the head done has been a real delay. Supposedly the guy who is doing the work broke his arm. I could have grown a whole new arm by now.
@@joepie221 I always hated having to rely on other people !!
That was a good joke for sure Joe. Thanks
It took some prep, but it worked out well.
nice one
Thanks
lol fun. I know it was faked but wondered how it was done.
smiling.
I just thouht that it was some kind of BS but never thought of April Fools
Total BS. Only once a year on this channel.
You rascal you. 😁
