Bubble Teleports Above Ground?

I've been designing a bubble script for a game that goes in front of your head and increases in size and damage based on a stat, and it increases faster based on a speed stat. However, it seems to hover over the ground instead of next to your head. I assume this is because it resizes faster than it cframes it in front of your player, but honestly I have no idea.

Here's the code:

local tool = script.Parent
local name = game.ReplicatedStorage:FindFirstChild("NameVal").Value
local player = game.Players:FindFirstChild(name)
local char = game.Workspace:WaitForChild(name)
local head = char.Head
local touchhit = script.TouchHit
local bubblegum = Instance.new("Part")
touchhit.Parent = bubblegum
bubblegum.Transparency = 0.4
bubblegum.CanCollide = false
bubblegum.Size = Vector3.new(1, 2, 2)
bubblegum.Shape = "Ball"
bubblegum.BrickColor = BrickColor.new("Carnation pink")
bubblegum.BackSurface = "Smooth"
bubblegum.BottomSurface = "Smooth"
bubblegum.FrontSurface = "Smooth"
bubblegum.LeftSurface = "Smooth"
bubblegum.RightSurface = "Smooth"
bubblegum.TopSurface = "Smooth"
bubblegum.Anchored = true

function onUsed()
    script.Parent.Enabled = false
    local thing = 1
    local size = player.Stats.Size.Value
    local speed = player.Stats.Speed.Value
    local clone = bubblegum:clone()
    clone.Parent = game.Workspace
    spawn(function (follow)
        repeat
            coroutine.yield()
            clone.CFrame = head.CFrame + head.CFrame.lookVector * thing
        until done == true
    end)
    for i=1, size do
        clone.Orientation = head.Orientation + Vector3.new(0, 90, 0)
        clone.Size = clone.Size + Vector3.new(1, 1, 1)
        thing = thing + 0.5
        wait(1 - (speed / 100))
    end
    done = true
    clone:remove()
    done = false
    script.Parent.Enabled = true
end

function onActivated()
    if not tool.Enabled then
        return
    end
    tool.Enabled = false
    onUsed()
end

script.Parent.Activated:connect(onActivated)

Here's a video of what happens (I increased my size and speed a lot to make it more noticeable): https://www.youtube.com/watch?v=EeT1wBio7co
