Euler's Disc Spins for Minutes

*******************
Falling has never looked as cool as when displayed by Euler's Disc.

Named after the famous mathematician Leonard Euler (pronounced oiler), this desk toy is an amazingly fun-to-watch demonstration of several physics concepts.

With a flick of the wrist, the heavy chrome-plated disc call fall for up to two minutes! The exact motion is known as sprolling (a combination of spinning and rolling), and it causes the disc to make circular passes around the center of the base while remaining upright as it slowly falls.

As the disc loses energy, the angle between it and the base diminishes and an interesting whirring sound is created.

A set of magnetized holographic foils can be placed on the top of the disc to create interesting visual effects. Turn out the lights, add a laser pointer, and the ensuing light show is nearly beyond belief.

Don't be shy; smart stuff is fun!

My friend once fell for 9 seconds. He tripped over a backpack strap and then got halfway up before twisting his ankle and falling again. He ended up on the floor in a fabulous position.

Euler's Disc will sproll (spin and roll) for up to two minutes! Watch it go!

Put this on a spinning Dark Side of the Moon record and I'm pretty sure you'll enter the fourth dimension

Is it bad that it made me feel uncomfortable that the disc didn't fall.

I was expecting the rave guy to say "COLORS!!" when there were lasers

The only reason im not clicking skip ad anymore is because most the time they're channel advertisements that are actually FUN to watch.
Gee, Companies NEVER thought that makign their commercials fun would work.

simplynaillogical would love this so much holo

[gavinurquhart]

one does not simply
"approach infinite" 

[khurramchandio]

I'm pretty sure simply nailogical will love the holo

Sigh.. Yes, guys, Euler = "oiler". "Eu" in German makes an "oi" sound, as exemplified in names like Marco Reus. If you go to Wikipedia (link: you can hear the actual pronunciation of his name. Learn some culture, people.

Do you know the situation if someone comes up to you and says "man this is so boring i rather watch objekts fall over"? Well now they made a toy out of this

[kenkaneki]

HOLO DISC! SIMPLY NAILOGICIAL/ CRISTONE WOULD LOVE THIS

[SHIFTKICK]

My physics teacher has this...pretty awesome (please more products like this and less like the fake snowballs)

[cwuzii]

$35?? What a rip off. Change the price to $5 and then we'll talk. 

[Imanota]

the noise it makes is something that i have always found amazing. i would get it just for the noise

♪You spin me right round, baby
right round like a record, baby
Right round round round
You spin me right round, baby
Right round like a record, baby
Right round round round♪

[yotamephmh]

You got all the physics right!
*tears of joy*

When I first saw this on Grand Illusions I already thought something along the lines of "Vat19 would probably sell this if they come across it".

[NepzRemix]

I have this. The amount of physics you can study from it is mind-boggling.
