How do you make something pop up then go away?

I have created a layer that I want to appear with shooting stars when correct. I put an animated gif on the layer for the stars. What can I use to then make it just go away again after a half second? 

I've tried several triggers for making the layer go away and none of them are doing what I need, which is to appear on a drag drop event, then go away right away and appear again on another drag drop event (and go away right away again). 

Thank you in advance for any help you can give.
