[DnD] What would happen if you put a Bag of Holding inside of a Bag of Holding?

Under the old rules, an earth-shattering kaboom as both bags are destroyed.  The explosion is so powerful it rips a whole in the fabric of space and time sucking everything in as a desperate attempt to patch the rift.  Fortunately, it is a localized effect.  Especially as rift usually closes very quickly.
