I created a animation for a custom model but it just flew away?

local animation = Instance.new("Animation")
animation.AnimationId = "https://web.roblox.com/catalog/4760001635"
-- Local variables
local animTrack = nil
local canPlay = true
 
function playShockAnim(Source)
    if canPlay then
        canPlay = false
        animTrack = script.Parent.Humanoid:LoadAnimation(animation) -- Load animation into Humanoid
        canPlay = true
        animTrack:Play() -- Start the animation
    end
end

how do I play my animation?
