How do I disable collision between players?

In some points of my game, it's problematic when players bump into each other when trying to solve fast-paced minigames. I tried this, but it didn't quite work, and something tells me it's not this simple.

game.Players.PlayerAdded:connect(function(player)
	player.CharacterAdded:connect(function(char)
		for _,v in pairs(char:GetChildren()) do
			if v:IsA('Part') then
				v.CanCollide = false
			end
		end
	end)
end)
