You have to wait until the fadeOut effect is done by providing a callback to it:
$(function() {
$('#hello').delay(1000).fadeOut('slow', function() {
$('#hello').show();
});
});
The .show() is getting called before the .fadeOut() has started.
Try this:
$('#hello').delay(1000).fadeOut(function(){
$('#hello').show();
});

In your example the show() function is being called before the fadeOut has finished. If you change it to:
$('#hello').delay(1000).fadeOut(function() { $('#hello').show(); });
Then the hello p element will appear again as soon as the fade out is complete.
It can, the problem is that .show() is being called before .fadeOut() due to your delay.
To fix it, try:
$('#hello').delay(1000).fadeOut().show(); //Will reappear immediately
or
$('#hello').delay(1000).fadeOut().delay(1000).show(); //Will reappear after 1 second
Use the fadeOut callback to specify the actions to do when the animation is over
$(function() {
$('#hello').delay(1000).fadeOut(function() {
$('#hello').show();
});
});
