The most unbelievabubble event of the year is back! Tomorrow afternoon from 3pm-5pm, hundreds of bubble lovers will pack Union Square to fill the park with magical floating soap for Bubble Battle NYC 2015. Considering going? Check out these awesome photos from last year's event to see what it's like to be surrounded bubble generators, toys and whimsical iridescent shimmers. Then wipe off those boat shoes and get out that bathing suit! The theme of this year's event is boat party.
