“Gender reveal party”

So my husband and I are finding out the gender of our twins on Friday and I just wanted to call and tell everyone. Well my mother in law was all mad we weren’t doing a “reveal party” so now we are having all the family over Friday night to announce the genders. Trying to think of something unique and fun to do for baby A and baby B. I was thinking of having my parents open Baby A/B to reveal and then having my husbands parents open the other. Any ideas????
