Private Gender Reveal ideas?!?

I'm looking for neat ideas to do a private gender reveal for just me and my hubby. I hope the tech will be able to write down the gender in a card so that we may find out in our own way (not by a stranger in a hospital) at our own timing. Any cute ideas you all have heard of where it's just a reveal between the couple?!? After looking on Pinterest, I noticed there's a lack of private gender reveals. Help!
