Me and my SO are not the type of people who show much emotion when getting presents or anything really. My Mom wanted to do a gender reveal but I thought that it'd be best not to because of the emotional thing. I have 33 days until we find out the gender.

So I thought it'd be cute to do something for my MIL and my mom to find out the gender. I only have one idea

Fill black balloons with (pink/blue) and have them on a board and let them throw darts at the balloons

Does anyone else have any similar ideas or situations
