Sarah’s Science Experiments with Dry Ice

Sarah Spivey’s Science Show: Fun and Accessible Experiments for All Ages

Discover the fascinating world of science with Sarah Spivey, a meteorologist who hosts the popular TV show GMSA@9 on Wednesdays. Follow along as she explains the science behind her experiments and demonstrates them live on KSAT.

Sarah’s experiments are in partnership with the San Antonio Zoo and are designed to be accessible to everyone, regardless of their background or level of understanding. To help you conduct your own experiments at home, here’s what you’ll need:


* DRY ICE BIG BUBBLE: large bowl, dish soap/water mixture, water, shoe lace or strip of cloth

* EXTINGUISHING CANDLE: Tea light, match, Tupperware or small bowl

* DRY ICE “INSTRUMENT”: Cups/containers of different sizes/shapes, water, soap


Now that you have all the materials you need, it’s time to start experimenting! Here are four simple and fun experiments that Sarah has demonstrated on her show:

1. DRY ICE BIG BUBBLE: Fill a large bowl with water and drop a little dry ice in it. Dip a shoe lace or strip of cloth in a soapy solution and drag it across the bowl, sealing the bowl with soapy water. You should see a big bubble form with vapor from the dry ice. Be sure to watch out for flying bubbles!

2. EXTINGUISHING CANDLE: Place a tea light inside of a Tupperware and light the candle. Place some dry ice around the candle and watch as it slowly extinguishes. This experiment is perfect for showing kids how heat can be used to control fire. Just remember to always use caution when handling fire.

3. DRY ICE “INSTRUMENT”: Place a small piece of dry ice on the table in front of you
