Experiment #1
We put food colouring and washing detergent in a glass beaker and then added dry ice. The dry ice reacted with the detergent and made a tower of colourful soapy bubbles. The bubbles were filled with carbon dioxide.
Experiment #2
We put some dry ice and water in a vacuum flask with the top plugged. Mist like stuff(carbon dioxide) came out of the little tube. When you blocked the little tube pressure would build up and the bung would shoot off.
Experiment #3
In this experiment Kevin put water and dry ice in a plastic container. Then he got a wet and soapy tea towel and tried to make a bubble over the top but he failed. So instead we just put the rest of the dry ice into the plastic container.
