Moms, anyone here who had a baby gender reveal party?

My college friend had this one conventional way baby gender reveal. She threw a normal party (I say it that way 'cause like any other party, we just ate, play some games and chitchat) and later when everyone's engaged already, herself and hubby placed this kind of cake (but cake in the photo is not the actual one, I can't find a copy, my bad) at the center. Everyone yells his and her guess and was so excited to see if blue or pink part of the cake comes out - at it was pink! :) We were so happy for the couple and also to get a taste of that yummy cake! hehe :D
