Eulers Disk

Price : $29.99

Eulers Disk - Euler's Disk amazes as it demonstrates the math and physics of spolling (spinning and rolling) of rigid bodies. Spin the included disk on the concave mirror and watch as the disk spolls for remarkably long periods of time.

This is an amazing toy! . Euler's Disk is a remarkably simple yet amazing toy. It employs simple principles of physics to do an amazing feat. You will never tire of watching it. Whenever i have new guests visit, I pull it out and it never fails to amaze them. Toddlers to senior citizens will all love watching it. It is a terrific investment, worth every cent!

One trick pony is still a good trick . I found this online from a store in the UK. I ended up buying it from Amazon because it was cheaper and I got Prime shipping. This toy is really neat. It only does one thing but it does it vey well. It just spins around in a mesmerizing way, making a strange noise. It spins for a long time and gets faster and faster until it stops with a sudden snap. Very cool. You will amaze children and your inebriated friends alike. I would recommend this to a friend.

USB Plasma Ball

Just wanted to point something out. . For a lot of you, this review will not be so helpful. For those of us who like to keep electronic devices constantly going for the aesthetics, ease of use and fun of it, though, this device may lack the durability you are seeking in a toy you could leave on and forget. As with all things of this nature, your mileage will very.About less than two hundred hours of non constant use, my plasma ball began to melt at the inside of its base. I stopped using it after I discovered this. That would explain my two star rating in that particular category.

This is neat . This is a neat little Tesla ball. It plugs into your USB, and is small so it doesn't take up room, but big enough to play with. If you get a USB AC adapter, it can plug into your wall too.

Plasma Ball . My kids really enjoy this and their friends have a lot of fun with it as well. They plug it in to the laptop and watch the electricity happen. They've had it for a week, but as soon as people come in, the ball comes out.

Fascinating to watch . My daughter loves to see the lights reach out to her fingertips when she touches it. Very cool.

Cons Review

Great little plasma ball . The first plasma ball I received was DOA right out of the box. This is understandable, as items like this are rather cheaply mass produced, and there usually isn't a whole lot of quality control (Thinkgeek is not the manufacturer, so they aren't to blame). What sets this particular ball apart however, is that it is sold by a reputable company (Thinkgeek) and a replacement was sent to me right away. The replacement works exactly as advertised, and it is a nifty desk accessory for sure.

For ten dollars plus shipping, I can't really complain too much about the build quality. If Thinkgeek wasn't reputable, and getting a replacement was a hassle, I'd be more inclined to complain. As it is though, I have every confidence that if this ball were to die, I could get it replaced by Thinkgeek's excellent customer service. I couldn't be happier with the customer service I received from Thinkgeek.

As for the actual ball, it is a small plastic sphere that is powered via USB (no batteries required). Once plugged in, it can be turned off using the On/Off switch on the base of the ball. Turning it on delivers eight to ten thin blue and pink/purple arcs of electricity, which can be focused into one bigger arc using your finger (if it is big enough) or palm. The arcs are easily visible with overhead lights on (or outside, I would assume) but are more easily viewed in darker situations. This may be redundant to point out, but this may be beneficial for some: This ball will absolutely not shock you, unless you are careless enough to place metal on it first, and then touch that (which is a bad idea with plasma balls; See any number of videos on youtube). I would recommend this item for a child, although I'd say that supervision is a good idea, as with all devices that are plugged in.

Awesome Plasma Ball . This is the perfect desktop trinket for a good price! I've been saying it's the best $20 I've spent since I got it :D
