String of Pearls

String of Pearls is a succulent plant. It has spherical leaves and tiny white flowers. I have the plant for over a year, but only today while strolling in San Mateo Garden Show I learnt its name. Before I had just refernced it as "small gree round balls". Now when I know its name, I can google search for it.
Searching taught me that the plant might be poisonous if ingested.
I have to keep eye on Itamar.
I learnt that I should place the pot over pebbless scattered in a dish that holds water.
I would like to propagate it to be able to share the plant with my friend.
The best instruction for propagating String of Pearls were:
Take a cutting.
Let it rest overnight.
Moist a Cacti soil.
Partially submerge the cutting in the soil.
Water once a week.
I will try it.
