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 bristle toothbrush, resembling the modern toothbrush, was found in China during the Tang Dynasty (619â907) and used hog bristle. The bristles were sourced from hogs living in Siberia and northern China because the colder temperatures provided firmer bristles.he first patent for a toothbrush was granted to H. N. Wadsworth in 1857 (US Patent No. 18,653) in the United States, but mass production in the United States only started in 1885. The rather advanced design had a bone handle with holes bored into it for the Siberian boar hair bristles.
