Step 4. Plant the star fruit tree in the hole so that the top of its root ball sits at least 2 inches above the ground (you may have to fill in more soil/compost mixture to get it to the right height). Fill the hole with the soil/compost mixture and tamp the soil down firmly with your feet to remove any air pockets.
The toothbrush consists of a plastic handle and nylon bristles attached to the head of the brush. Contemporary designs offer a variety of styles and shapes in a market that has swelled to $600 million in the mid-1990s, in part because of price increases, but also because toothbrushes are replaced frequently.
The first âtoothbrushâ (with bristles) was invented in China and was made of animal bone, bamboo and hog hair. The bristles were very hard. William Addis of England invented the first mass-produced toothbrush. While in prison, he drilled small holes in a cattle bone, tied swine fibers (from wild pigs) in bunches, passed them through the holes and then glued them. The first three-row bristle brush was designed by Dr. Meyer Rhein.
