Absolutely amazing.....   I have to buy a pair of these.  These would be the perfect stocking stuffer for a child or an adult.
 
This video of them being demonstrated is also on the page linked above, but here's a direct link to a WMV of it:

There are also some other very cool toys and gadgets on this site.  You'll be glad you checked it out.

That would have made Inception worth watching.

 

[Tronz]

That's cool.

I'm just wondering how the hell they managed to weld those together! 

 

[JoonBug]

That's unreal!!! 

 Thanks for the link.

electric arc?

I wonder how fast those will go with an air compressor xD

 

[Armaegis]

Over 9000?

Very cool but $46.00 is a bit steep.

Agreed. Welding two ball bearing + a plastic straw + a cardboard box package = $46?!

Yes, certainly pricey.  But unless you have a welder with 800 amps of current, not sure how you would make your own.

Maybe a bit of J-B Weld instead?
