My explosion doesn't destroy any parts how fix?

I've commented on the important parts So this is just a lightning storm script it makes one Invisible explosion at the raycast Instance and Breaks its joints and unanchors it then It makes a visible explosion at the last point of the lightning It pretty much just does nothing to the houses. What happens: https://gyazo.com/9788f1e4bb7fedfa2450f05db36a3c5b I've tried altering it a LOT but still pretty much nothing Please help After a bit it finally destroys some parts but they fall in slow Motion
