How do i make a part grow only up?

I found this tweensize script

local TweenService = game:GetService("TweenService")
local Part = script.Parent

local info = TweenInfo.new(
	5, 
	Enum.EasingStyle.Linear,
	Enum.EasingDirection.Out,
	0,
	false,
	0
)
wait(3)
local Goals = 
	{
		Size = Vector3.new(2,2,1);
	}

local MakePartBigger = TweenService:Create(Part, info, Goals)

wait(5)
MakePartBigger:Play() 

The problem is that the part grows in both directions, up and down an i need it to only grow up what should i do?

Make sure to add half of the part y axis size to the position/cframe

Lets say

goals.Size = Part.Size + Vector3.new(10,50,20)
goals.CFrame = Part.CFrame + CFrame.new(0,-25,0)

Vector3.new(0,y,0) just use axis y if you want up and down

Ok for this you need to grow it specificly on the y axis, so for example if you're doing script.Parent.Size = Vector3.new(2, 2, 1) the middle number is the y axis, so you would only make the middle number go higher. Just incase if you still don't understand I'll put the fixed code in.~~~~~~~~~~~~~~~~~ local TweenService = game:GetService("TweenService") local Part = script.Parent

local info = TweenInfo.new( 5, Enum.EasingStyle.Linear, Enum.EasingDirection.Out, 0, false, 0 ) wait(3) local Goals = { Size = Vector3.new(0,2,0); }

local MakePartBigger = TweenService:Create(Part, info, Goals)

wait(5) MakePartBigger:Play()
