love this machine. it is on my must have list (along with centaur, rolling stones and fathom from this era). someone else recently was telling me about these backglasses exploding in their hands. anyone know why that happens?

Have heard of backglasses expoding a few times in peoples hands....would say it would be the differences in temperature from the persons hands and the glass. Same with placing backglasses (and playfield glass) directly on the ground against the wall when the floor is cement. ALWAYS place a towel or something similiar down first!
