Ideas for gender reveals?

I am keeping my pregnancy a secret from everyone who is not immediate family/friends, and I’m putting together a little collage video of smaller videos I’m taking along the way to post on social media at the end for all my friends/family on social media who will have missed out, I decided I want to do a small gender reveal to my friends/family who know as individuals and video their reactions and add that to the collage but I can’t think of a small way I want to do it for each individual person. Any ideas?
