Broken Wine Glasses? Don't Fret; Model Gravitational Lensing, Instead!

Today, I purchased two very expensive crystal wine glasses to replace ones that I have broken.  On the way home, I broke them.  Accidentally.  Not to worry!  Now I can use the bases as very expensive crystal "gravitational lens" modeling tools.

In  this TED Ed video that I saw (amaaaaaaaaaaaaaaaaaaazing), physicist Patricia Burchat explains dark energy and dark matter in such a fascinating and interesting way.  I would love to have her as my physics professor.  In the video, she explains and demonstrates the use of a wine glass bases as a "gravitational lens" that bends space/time and light.
Watch it!  So good.
