? Watch the video of Sarah’s school science experiment here!

Hello parents, teachers and students! Yep…I’m sure you’ve heard of this classic. Science with Sarah for the 2022-2023 school year ends with a bang. Here’s how you can do it with your kiddos.

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

Science with Sarah: Invite KSAT to your school for live science experiments. (KSAT)

HERE’S WHAT YOU’LL NEED

A piece of paper
Scotch tape
Index card
Roll of Mentos
2L Diet Coke bottle (the smaller ones don’t work as well)

DO THE EXPERIMENT

Make a Mentos dispenser by rolling up a piece of paper and taping it into a tube shape
Stack the Mentos into the paper tube. You’ll use the index card to keep the Mentos in the tube until it’s time to drop them into the Diet Coke.
Unscrew the 2L Diet Coke bottle and place it on the ground
Drop all of the Mentos into the Diet Coke bottle using the paper tube and index card, step back and watch the geyser launch into the sky
