Sarah’s Science Experiments with Dry Ice

Discover the magic of science with Sarah Spivey on GMSA@9 every Wednesday! Parents, teachers, and students are invited to tune in and watch Sarah’s live demonstrations, as she explains the science behind them. This program is brought to you by the San Antonio Zoo in partnership with KSAT 2023 – All rights reserved.

Want to try some of Sarah’s experiments at home? Here’s what you’ll need:

* Dry ice (NEVER HANDLE DRY ICE WITHOUT GLOVES)

* 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

* Billions of Bubbles: Water, soap

Follow these simple steps to conduct your own experiments:

DRY ICE BIG BUBBLE:

1. Fill a large bowl with water and drop a little dry ice in it.

2. 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.

EXTINGUISHING CANDLE:

1. Place a tea light inside of a Tupperware and light the candle.

2. Place some dry ice around the candle and watch as it slowly extinguishes.
