effervescent

Effervescent first described drinks: Latin effervescere, to boil up — the fizz that rises when you open a bottle. Said of a person, it means bubbling over with lively, happy energy that spreads to everyone nearby. An effervescent host saves a dull party. It is brighter than cheerful and lighter than excited. In the animation, a man bursts with joy and bubbles fly off him like soda.
