How do i make a part disappear and become untouchable for 5 seconds?

I am making a Spleef-like game, and I am having difficulties with the pieces i need to disappear. Specifically, i have been trying to make a brick go invisible and untouchable, effectively making it disappear, for 5 seconds, then reappear. But once a player touches it, he needs just enough time to run away, so he does not instantly fall. Help?

Hi...(I cant test this right now but it should work) you would need to use the transparency and cancollide property's. This isnt really a request site either but

part = script.Parent--this is making a variable part is the scripts parent so make sure the script is in the part.

function invisible()-- this is making a function so we can make this script.
	part.Transparency = 1 -- So we made the transparency invisible
	part.CanCollide = false-- and where u can walk through it
	wait(5)--were waiting 5 seconds then
	part.Transparency = 0 -- Its visible
	part.CanCollide = true --You cant walk through this
end --end
invisible() --we are calling our function

Like I said I cant test this right now but it should work. Hope this helped let me know if it did.

Place this script in the part, along with a ClickFunction:

function turnInvisible(part)
	part.Transparency = 0
	wait(1) --We have now waited 1 second
	part.Transparency = 0.2
	wait(1) --We have now waited 2 seconds
	part.Transparency = 0.4
	wait(1) --We have now waited 3 seconds
	part.Transparency = 0.6
	wait(1) --We have now waited 4 seconds
	part.Transparency = 0.8
	wait(1) --We have now waited 5 seconds
	part.Transparency = 1
	part.CanCollide = false
end
script.Parent.ClickDetector.MouseClick:connect(turnInvisible(script.Parent))
