Cabbage juice! Yes, it's a real thing. While it sounds gross, Ana and Angel have actually found a good use for it. It turns out that if you pour cabbage juice into a glass of water and baking powder it turns blue. If you pour it into white wine vinegar, it turns pink, so they made a gender reveal game out of it.
Speaking of gender reveals, not all of them go so smoothly. A mom had a mystery balloon and a captive audience. She also had a balloon full of helium and she was outdoors, so her gender reveal soon became an impromptu weather balloon experiment. It looks like the birds will get to find out the gender first!
