Gender reveal for twins?

Dennyiel • Married to my high school sweetheart ;) we have four beautiful children a boy and girl, and a new set of boy/girl twins! Had a chemical pregnancy in September 2015.anovulation problems
Okay so we find out on the 30th what our sweet little nuggets are. I have 2 older children 10yr old son, 9yr old daughter and I want to include them in our gender reveal. Anyone have any cute ideas or what did you do? I've searched places like Pinterest but not much for twins.
