How to make a Block Change Transparency in Spleef?

I am trying to make a script for spleef. The script is a regular script in the part in workspace. Here is the script. How do I make it so that the part (SpleefP) Will make the transparency stop at 0.9?

game.Workspace.SpleefP.Touched:connect(function(hit)
for i=1,9 do
	       wait(0.1)
	        game.Workspace.SpleefP.Transparency = game.Workspace.SpleefP.Transparency + 0.1
	    end
	end)

SpleefP is the part name. I figured that since the transparency is set to 0 automatically then you would have to ADD 0.1
