What are some ideas on how to create a terrarium with earthworms, morning glory and potting soil?

Question

its all in the question, please all ideas are welcome

Answer 1

Place cardboard and coffee grounds under the potting soil for the earthworms. Keep the soil moist, but not wet.

The morning glories are going to be a problem unless you are allowed to let them grow out of the container. The vines require a lot of room and will seek sunlight. They are very easy to train. Once the vine starts to grow, place a weight (rock) with a string tied around it near the vine. Tie the other end of the string above the terrarium (if inside, near the ceiling).

Instead of a string, a cane pole or balsa wood sticks can be used.
