2. Second go and get a aquarium from the Pet Store (until then I stored them in a coffee jar.

3. Then put the glass pellets & the statue in so the snails can play on them.

4. Then put the cabbage, chalk, leaves & the plant in for the snail to eat.

5. Then put the snail/snails into the biosphere.

6. Then put the  bottle top filled with water inside the biosphere.
