It's a little pewter basket with a bubble blown around it with some bubble mix, when water drops from little gadget it goes right through little bubble to form crown in water in little basket. The bubble doesn't break right away but eventually it does..
The water is dropping into little pewter basket, right through bubble blown onto basket. The drop goes through bubbles a few times without breaking.. The rest is done (timing & flash) with time machine/drip kit..
