Make a Big Dry Ice Bubble

                                                                      
Have fun making a dry ice bubble that will grow and grow as it fills with fog. This experiment is a great one for adults to do with kids. Add water to the dry ice, cover it with a layer of soapy water and watch your bubble grow, how big will it get before it bursts? Give it a try and find out!

What you'll need:

• Water
• A large bowl with a lip around the top (a smaller bowl or cup will work too)
• A strip of material or cloth
• Soapy mixture for making bubbles (water and some dishwashing liquid should do the trick)
• Dry ice - one piece for a cup, more for a bowl. Places where adults can buy dry ice include large grocery stores and Walmart. Butchers and ice cream stores might have some too.
