I'm not too sure how your game works, but for example:
Create a new rule under Balloon for collision with 'Arrow'
Then use Interpolate on the Balloons Alpha from 1 to 0 over thge course of 0.5 seconds. Then create a timer below the interpolate for 0.5 seconds with a Destroy actor in it.
It should then disolve until invisible, then delete itself.
