Unbreakable wine glasses?

Tired of fragile crystal wine glasses that break when you wash them? The German glass manufacturer Schott Zwiesel has created a series of wine glasses called “tritan”. They are virtually impossible to break (it is said) and in addition they do not contain lead (as traditional crystal) but titan. Here is a fascinating video of how you can hit the glass with a steel ball without breaking it (www.schott-zwiesel.com/html/tritan_filme.htm, click the upper right video).
