The soap mixture :
Pour 50 mL of water and add 10 g of sugar and mix the ingredients in a large jam pot. Add 40mL of dish soap. DO NOT STIR ! Add 20 mL of glycerin. Stir GENTLY ! Add 80mL of water.Stir again.
Now let's make a giant dry ice bubble !:
Fill 2/3 of the basin with water. With your oven mitt, take a piece of dry ice put it gentle in the water. Do no throw it ! Dip your fabric in the soap mixture. Strech it and slowly rub it along the edge of the basin in order to create a single bubble. Wait for the bubble to grow and burst.
It creates a cloud. The cloud is made of water because anhydrous copper sulfate becomes blue.
