Have you ever cloned another living thing?
It takes a little time but if you use the forgotten cloning coffee can, you can grow a genetically identical copy of a rose plant, a fig tree, a ficus or many other plants.
In this activity you can cause a part of a stem to grow roots. When the roots have grown for a few weeks, the stem can be cut away as a new and independent plant. This is also a way to create many brand new and free plants from a single parent plant.
