Quick and easy gender reveal ideas?

Samantha • Mommy of one born September 2017 💙

Sharing the news of our second baby’s gender this weekend with our parents and siblings. Any ideas on what to do? They aren’t expecting to find out, so I can’t show up with a smoke bomb or a balloon or something 😁

I was thinking we all show up in blue and see if anyone notices, but they are all so oblivious I don’t think they will 🤣

Any other ideas??
