While this rendition isn’t going to get the same results as a real particle accelerator, I invite you to take a look at this fantastic LEGO version from Jason(JK Brickworks).

This “working” accelerator does in fact send a LEGO soccer ball around the track at 440 studs per second, or approximately 12.5 km/hr. Jason outlines some of the build in more detail on his blog.

I highly recommend checking out the video, too.
