Part0 = Instance.new("Part")
Part0.Parent = game.Players.LocalPlayer.Character
Part0.Position = Vector3.new(102.359985, 2, -106.899994)
Part0.Transparency = 0.5
Part0.Size = Vector3.new(4, 4, 4)
Part0.BottomSurface = Enum.SurfaceType.Smooth
Part0.Material = Enum.Material.Glass
Part0.TopSurface = Enum.SurfaceType.Smooth
Part0.Shape = Enum.PartType.Ball
How would I get this to expand in a loop, and make the function input a certain amount?

I am not sure what are you trying to do. Your script is local, other players will not see the orb. Is that intentional? Also you have put weird coordinates, did you try to attach the orb to a character? Parenting is not sufficient for that.
This is just a test run, I'm trying to see how the orbs physics work.
Sleazel is wrong. Don't listen to him lol. As for the loop, i'd recommend a while loop where you update the size by (.1, .1, .1)
Cant the tweening service work with size?
