🧪 Science with Sarah: Soda bottle rockets! 🥤

“Lift-off” with this fun, chemistry-driven science experiment!

Hello parents, teachers and students! If you’re looking for a fun way to explore literal rocket science, this experiment is for you.

Be sure to check out GMSA@9 on Wednesdays when Meteorologist Sarah Spivey does the demonstrations and explains the science behind it.

HERE’S WHAT YOU’LL NEED
