Touched is only working for character parts not other parts?

Touched is only working for character parts not other parts. https://www.youtube.com/watch?v=YM3ca5cArYo&feature=youtu.be < I tried to make the blue part turn other parts Transparent.

Tele.Touched:connect(function(otherPart)
  if otherPart ~= game.Workspace.Baseplate then
  otherPart.Transparency = 1
end
end)

Parts required to be touched by something moving without script commands. This has happened to me before.

I know this because when I moved a part into another, it did not activate the function but if dropped from the air, it would activate.

So basically it's gotta have gravity or a character to activate it.
