Surprising my mom with gender?

So I took the blood test, and will be finding out the gender this week. My mom won’t be in town so I can’t do a gender reveal for me, but she’s a first time grandma and she swears it’s a boy lol. I want to do a gender reveal where I give her something and it says the gender because she’s super excited and first time grandma! I feel like balloons is dumb because that’s for the mommy of baby finding out My fiance isn’t going to know either I want it to be super cute! Any ideas? Please no rude comments i know this is unique
