In the YouTube video they explain that CRTs have a layer of safety glass in front of the actual screen to protect viewers in the event that the screen implodes. You were actually trying to break through multiple pieces of glass! I've taken a crowbar to a broken CRT before for fun and can confirm that it takes a lot more effort than one might think.
It depends on the CRT. Some use steel bands wrapped around the edge of the faceplate and tightened to keep the glass in compression where it's strongest.
