Gender reveal?

Ma

So we will find out the gender in a few weeks and I was thinking of doing a small gender reveal with just our parents. I want us all to be surprised at the same time but I'm having a hard time coming up with a fun simple mess free way to do this. My husband could care less about our families. He just wants to know lol. I want our parents to be included and have fun with it since it is our first child. The main problem is my family is WAY crazy about these kinds of things and his is more low key. I really don't what it to become a big thing but know if we don't atleast do something my mom will be disappointed. Any ideas?

Or if any of you have a gender reveal planned or had one already I would love to know what you did!
