Why aren't my magma drips smooth, and puddles are laggy even with debounce?

local Debris = game:GetService("Debris")
debounce=false
while wait(math.random(0.7,1.5)) do
    if debounce==false then
        debounce=true
        drops = script.Parent:Clone()
        drops.Anchored=false
        drops.Size = Vector3.new(0.257, 0.78, 0.295)
        drops.Position = Vector3.new(script.Parent.Position.X-0.5+math.random(0.4,0.8),script.Parent.Position.Y,script.Parent.Position.Z-0.5+math.random(0.4,0.8)) 
        drops.Parent = workspace 
        debounce2=false
        drops.Touched:Connect(function(hit) 
                if debounce2==false then
                    debounce2=true
                    local x=game.ReplicatedStorage.Magma.ExplosionZX:Clone()
                    x.Parent=workspace
                    x.Position=Vector3.new(drops.Position.X,34.137,drops.Position.Z)
                    Debris:AddItem(x, 1)
            end
        end)
        Debris:AddItem(drops, 1)
        debounce=false  
        debounce2=false
    end
end

It's crappy, chalky, and laggy. I would love to develop for these up-coming anime games but I just don't seem to have the skills, I try really hard but it's not good enough.
