Are you a parent, teacher, or student interested in learning more about science? Be sure 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 brought to you by the San Antonio Zoo (Copyright KSAT 2023 – All rights reserved).
If you’re looking to conduct your own science 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
Here are the steps for each experiment:
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.
