Science with Sarah: Dancing Dry Ice Bubbles and More

Sarah’s Science Experiments with Dry Ice

Watch the video of Sarah’s science experiment at Helotes Elementary School here! Parents, teachers, and students are invited to tune in to GMSA@9 on Wednesdays when Meteorologist Sarah Spivey does the demonstrations and explains the science behind it. Science with Sarah is a partnership with the San Antonio Zoo (Copyright KSAT 2023 – All rights reserved).

If you’re interested in hosting a live science experiment with Sarah and David, simply fill out this form. “Winners” will be selected at random. Keep reading to learn how to conduct your own experiments at home.

Here’s what you’ll need for the experiments:

– 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

Step 1: Fill a large bowl with water and drop a little dry ice in it. You should see some vapor from the dry ice. Step 2: Dip a shoe lace or strip of cloth in a soapy solution and drag it across the bowl. Seal the bowl with soapy water using your hand or another piece of cloth. You should see a big bubble form that looks like it’s floating in mid-air! Step 3: Keep an eye on the bubble as it slowly loses its shape and eventually disappears completely. Repeat these steps until you have perfected your technique!
