How do i change player size when stepping on a brick?

I want to change the player size like the size could become small or big when stepping on a brick but I don't know how.

local scale = 2

script.Parent.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		local humanoid = hit.Parent.Humanoid
		humanoid.BodyDepthScale.Value = scale
		humanoid.BodyHeightScale.Value = scale
		humanoid.BodyWidthScale.Value = scale
		humanoid.HeadScale.Value = scale
	end
end)

Change scale to change how far you scale. Also plz mark me as answer :P

local ScaleCharacter=require(4657682015).ScaleCharacter
local newsize=5 
local tab={}
script.Parent.Touched:Connect(function(v)
local char=v.Parent
if char and not tab[char] and char:FindFirstChildOfClass"Humanoid" then
tab[char]=true
		ScaleCharacter(char,newsize)
		char.Changed:Connect(function()
			if not char.Parent then tab[char]=nil end
		end)
end
end)
