Sir Isaac Newton vs. Andrew Brunt

So I wonder if Sir Isaac Newton ever added the scientific factor of Andrew into his equations. He came up with the amazing idea of kinetic energy. Put together the great model of the metal balls. William was so intrigued with them at the Clark Planetarium that he had to have a scale model for home. He carefully placed it on his dresser. What he didn't plan for was his younger brother. I haven't discovered all of the facts, but the end result.....

Speaks for itself.....

I told Andrew, after spending an hour or more getting them untangled, that he cannot play with his brothers' balls anymore.
