Is the "Explosion" mesh Anchored? Because Touched doesn't fire on anchored parts.

Well you have some erros from the script, but Touched only fires if the "Hit" is from Physical Simulation, and not from setting the CFrame or Position of the Parts. I think that's why the Touched is not firing.
IDK exactly how to achieve the explosion damage, but you may try using something like magnitude or region3
