Why isin't this set transparency brick working?

Hello. The problem is that you have a wait(60) in the loop meaning it'll have to wait one minute before going on to the next part, meaning that it would take five minutes for the part to turn invisible. Instead, make a separate loop that makes the EndParts visible again with a wait in between the two loops. Try this:

local Part = script.Parent

local EndParts = {game.Workspace.TEndPart, game.Workspace.DEndPart, game.Workspace.Neon1EndPart, game.Workspace.DessertEndPart, game.Workspace.ASHEndPart}

Part.Touched:Connect(function() 
	for _, object in pairs(EndParts) do 
		object.Transparency = 1 
		object.CanCollide = false 
	end 
	
	wait(60)

	for _, object in pairs(EndParts) do 
		object.Transparency = 0
		object.CanCollide = true
	end 
end) 

If you want it to happen when a humanoid/player touches it, do this:

local Part = script.Parent

local EndParts = {game.Workspace.TEndPart, game.Workspace.DEndPart, game.Workspace.Neon1EndPart, game.Workspace.DessertEndPart, game.Workspace.ASHEndPart}

Part.Touched:Connect(function(otherPart) 
	if otherPart.Parent:FindFirstChildOfClass("Humanoid") then
		for _, object in pairs(EndParts) do 
			object.Transparency = 1 
			object.CanCollide = false 
		end 
		
		wait(60)
	
		for _, object in pairs(EndParts) do 
			object.Transparency = 0
			object.CanCollide = true
		end 
	end
end) 

When the part is touches, it'll check for a humanoid. If it has one, it'll continue the script.
