@tinyrobin.com: Balloon that blows up on its own! 🎈 Just mix baking soda and vinegar, no blowing needed! The reaction makes carbon dioxide, and that’s what fills the balloon. So cool and super easy to try at home with kids!💨✨ #ScienceForKids #BalloonExperiment #FunLearning #STEMKids #PreschoolScience
