Eulers Spinning Disk - Fascinating Desktop Illusions -- Spin the holographic disk on the mirror - does it speed up? Listen to its rhythmic sounds. Why does the humming get louder as the speed of the disk increases? Complete with instructions and the scientific answers!
This review is from : Euler's Spinning Disk
Fascinating! . I had never heard of Euler's Disk until I received it in the mail; a gift from my daughter. A simple twist of the heavy chrome-plated disk that you set on top of a concave mirror (furnished) starts it spinning at an increasing rate for at least two minutes. As it spins faster it generates a mysterious tone and changes appearance depending on which holographic magnetic designs you attach and depending on your lighting. You can Google Euler's Disk and learn how it was developed and the science behind it. But unless the manufacturer does a better job of promoting this device you will never read this revue because you won't know to look for it. Sad.

Euler's Spinning Disk Reviews
Great gadget for engineers and technical types . I am an engineer, and I enjoy showing this to my engineering and technical pals. Everyone is amazed at how long this thing spins. I bought a second one for my father.

Euler's Spinning Disk Opinions
Captivating little gizmo . This was a Christmas gift for a 14 year old, but the whole family loves playing with it. We kept it on the table during family card games. It's fascinating to watch, especially with the interchangeable holographic magnetic sheets that you can attach to it to change the patterns. The heavy magnetic disk looks like a 3-D ball or oval as it spins, picking up speed before the disk comes to a stop. The sound shifts in intensity until it sounds almost like small motor running. Loops of light appear near the base. It's fascinating.

Fun for a while . I bought this as a Christmas gift for an eleven year old boy. It's one of those things that everyone is amazed by for a couple days, and then it gets put away until it's eventually sold in a garage sale. It would be better as an educational aid in a classroom getting used year after year, but it's not the greatest as a "toy". It is pretty cool though!
Educational and fun . It was fun to show it to different people, but once you run out of crowd there was not to do with it... The magnet stickers add some fun but I guess special lighting is neccesary to really enjoy them.
spinning . I used this is my classroom for several years--now my 4 yr old niece is fascinated so I began to hunt her one. She spins and spins and spins--but note: the spinner is heavy and can break glass!
More than a toy: science-head engineer geek nerd fun. Lots of it. . This toy was an unexpected surprise. And it's more than a toy, it's a repeatable science demonstration in your home.
Any nerd of any stripe will love this thing. MD, engineer, programmer, biologist, there's something that any and all of them will be able to relate to from within their fields. It's an excellent conversation piece. And kids will be fascinated with this for a surprisingly long time.
It must be noted that while the whole kit is simple, the materials are of very high quality, the stainless steel disk is heavy, and very precisely machined. I anticipate that it will last years. It will be one of those items you put away in time but will bring out again and again.

Surprising . It goes for a long time. It's enjoyable to watch. Haven't played with the different plates much yet, but it makes some cool designs.
Buy something else . If I had it to do over again I would have ordered a pizza-all-the-way.
People are starving all over the world. Give $20 to the homeless.
OK, ever spin a coin and watch it? Holographic? 3D? NOT! That's it. It spins. Makes noise while spinning.
Come to think of it, spinning a pizza would be more entertaining.
Challenge your friends to catch a piece of pepperoni! Fun for the whole family!
I feel like a fool. Don't join me.

misleading . what a waste of money, unless you have the blood of Thor in your veins this disc will only spin for 10 to 20 seconds, even if you can bench 400ibs, it only spins for about 1 minute or so, and you have to be accurate in spinning, you must be able to spin this in one place, I can do this because I have always been a good coin spinner with one hand, and even though I can bench about 300lbs, I still find it very boring and difficult.
good idea, though they are not totaly truthful in the advertising...I give one star,because I don't know if I can give no stars.
