Problem with collision in a blood system. [ ? ]

So, I was making a blood system inspired by Blood Flow, and it works fine. But, it have a problem: It's not detecting collisions. What it should be: When the meatball fly off your body and something touchs it, a blood splat appears in the same positions has the meatball, but it isn't detecting collision. If I turn CanCollide true, it don't detect collision, if I put CanCollide false, it don't detect collision too. People said to I use Raycasting, but I don't know how could I do that. Here's my code:

--//Players\\--


local Players = game:GetService('Players')


--//Workspace\\--


local BloodParts = game:GetService('Workspace').BloodParts


--//ReplicatedStorage\\--


local ReS = game:GetService('ReplicatedStorage')


local BloodMeshes = ReS.BloodMeshes


--//RunService\\--


local RuS = game:GetService('RunService')


--//TweenService\\--


local TS = game:GetService('TweenService')


--//Delay and Others\\--


Debounce = false


--//Scripting\\--

    Player.CharacterAdded:Connect(function(Character)


        local Humanoid = Character.Humanoid


        local OldHealth = Humanoid.Health


        Humanoid.HealthChanged:Connect(function(NewHealth)


            local HealthDifference = OldHealth - NewHealth


            OldHealth = NewHealth


            if HealthDifference <= 0 then


                return


            end


            local NumberOfDrops = math.floor(HealthDifference)


            if Debounce == false then


                Debounce = true


                for i = 0, NumberOfDrops do


                    local MeatBall = BloodMeshes.MeatBall01:Clone()


                    MeatBall.Position = Player.Character.Humanoid.RootPart.Position + Vector3.new(0, 2, 0)
