Kids usually look upon brushing teeth as a boring and tedious process, so we wish to make tooth-brushing more interesting and raise a kid’s will to brush his teeth.
The toothbrush is designed to be a dolphin shape which
not only attract children but also easily to be held.
A two-color oil and water separation material is placed within the brush handle. When a kid is brushing his teeth, the shake of the handle mixes the oil and water temporarily, creating different colors and attracting the kid’s attention.
