The 5" string length provides a pendulum length of 4.496" to the 4.3g nickel plated stainless steel balls each 0.876" in diameter. Overall, the unit weighs in at 1.65lbs and is a perfect gift anyone who is nerdy, into science, geeky, or just generally awesome. It also looks pretty good on anyone's desk. It comes disassembled, and while it's pretty easy to put together, you must very careful and delicate while assembling it. The strings can warp easily and will make the cradle out of alignment.
