Explosion.Hit not correctly working?

Explosion.Hit doesnt exactly work correctly for whatever reason. this is the first time i've had this problem. When the part explodes and hits all the parts around it; it only prints one part.. instead of all the parts it hit. and also doesn't change the brick color. Any help please? Would be greatly appreciated!

script.Parent.Touched:Connect(function()

    local explo = Instance.new("Explosion")
    explo.Parent = game.Workspace
    explo.BlastRadius = 5
    explo.Position = script.Parent.Position
    explo.Hit:Connect(function(partHit)
        print(partHit)
        if partHit.Name == "Part" then

            game.Workspace.PARTsHit.Value = game.Workspace.PARTsHit.Value + math.random(4,12)
            partHit.BrickColor = BrickColor.new("Black")
            script.Parent:Destroy()
            else

    wait(0.01)
            script.Parent:Destroy()



    end
    end)
    end)
