BruxZir® Solid Zirconia vs PFM Hammer Test

I do enjoy this simple experiment showing a BruxZir® Solid Zirconia crown being driven into a piece of timber by a conventional hammer.  The crown remained fully in-tact, whereas its PFM counterpart was mostly reduced to dust.  I for one found this experiment far more entertaining than agreeable charts and numbers!
