- Gloves                                                               - Solid carbon dioxide

- Basin with a large rim                                        - Water

- Strip of fabric                                                    - Dish soap

- Graduated cylinder                                          - Sugar 

- Weighing scale                                                - Glycerin 

- Small dish 

- Spoon 

Protocol : 

     To make a bubble with dry ice, you must : 

•  Stir water, sugar, dish soap and glycerin 
•  Put the dry ice in the basin with 2/3 of water
•  Dip your fabric in the soap mixture and stretch it and slowly rub alobg the edge of the basin

       To make an explosion, you must :

• Put the dry ice in boiling water (100°C)

Changes of states :

First, vaporisation hot water becomes gas, second sublimation solid carbon dioxide becomes gas and the third condensation 

• The bubble grows up and explodes
•  When you put some anhydrous copper sulfate under the cloud that's become blue

•  The cloud is made of water
