Maybe you already know this easy trick for a really bubbly bubble bath—but I just learned it. Instead of waiting until the bath is full and then adding the bubble bath (which always seems to require quite a lot to make it bubbly enough), add the liquid at the very beginning when there is barely any water (just make sure the drain is already plugged). It requires much less liquid and creates tons more bubbles. Children also love watching the bubbles build as the water fills.
