    • A dental floss stick comprises an upper piece 1 and a lower piece 2 which are both U-shaped, the top of both arms of the U-shaped upper piece 1 and lower piece 2 being rotatably connected by joints. The upper part of both arms of the upper piece have a bulge 3 while those of the lower piece each have a corresponding groove 4. Further, the middle parts of the upper piece and lower piece comprise a female buckle 5 and a corresponding male buckle (10, fig.6) respectively, with the upper piece further comprising a handle 9. A dental floss (7, fig.1) extends between both arms of the upper piece, wound or tied to each arm above the bulge 3. Meanwhile, a blade (8, fig.5) is located at the position of the groove 4, arranged to cut the dental floss when the upper piece 1 and lower piece 2 are brought together by rotating. The dental floss stick can be reused by replacing the floss.

    • Disclosed is a hydroponic apparatus for culturing edible sprouts mainly including a top cover, a growth lattice, a shoot lattice, a movable flat cutting means, a first net fixing lattice, a movable net, a second net fixing lattice, and a bottom tray for collecting water, each sequentially superposed on one another from top to bottom. When the sprout crop has grown sufficiently, the top cover is placed onto the growth lattice, and the flat cutting means is first inserted into the hydroponic means between the shoot lattice and the first net fixing lattice to cut off the root portions of the sprouts. Then, the movable net, the first and second net fixing lattices, and the bottom tray with the cut root portions are removed and the rest of the culturing is turned upside down. The flat cutting means is then inserted into the slits formed on the top cover to cut off the top portions of the sprouts. The remaining middle portion of the sprouts can be then washed clean and be packed for use later. A timer can be connected to the hydroponic means for automatically supplying water to multiple units of the hydroponic means superposed on one another in an outer container.
