The touched event in my explosion is not working?

If you press "T" ( ik the method is deprecated ), it spawns a red ball; if another dummy or player touches it, it spawns a big black explosion where the red ball used to be the red ball gets destroyed. Everything that touches the explosion except your own character model just gets destroyed. the problem is that the other dummies don't die.

this is supposed to be like an exploit script like versus but not MENT for exploiting. its just a fun test

apologies for the broken lines in the end and apologies for how long it is

EDIT: i accidently made the dummies root part anchored still I appreciate if u guys could find a way to destroy the dummies, even if the root part was anchored
