I've also had times when I added them to water or other drinks, only to, once again, splash.
I have finally developed what I call the Plinko method. If you've ever watched The Price is Right, you know Plinko and how they slide the chips against the flatness of the game board to let them slide gently downward. Hey, it works really well with ice cubes!
Now I just drop (I mean, slide) them, one at a time, from the lip of the glass/mug/whatever, against the side, and let them slip gently into the beverage.
Simple - but here I am at 76 only now discovering that!
