A writing & candy utensil for giving a user something sweet to chew on rather than the end of the writing utensil. The writing & candy utensil includes an elongate tubular member having open front and back ends; and also includes a writing tip being disposed at the front end of the elongate tubular member; and also includes a candy support assembly being removably attached to the elongate tubular member; and further includes a piece of hard candy being removably supported by the candy support assembly.

Writing and candy utensil

A teaching apparatus or teaching tank which has two, a front and a rear, substantially planar walls at least one of which is transparent. A plurality of bolts and spacers, or molded fasteners are used for holding the front and rear walls in parallel opposed spaced relationship to form the tank volume which tank volume is defined by the planar dimensions of the front and rear walls and the tank cavity width which width is determined by the spacers. The tank side walls and bottom are formed using flexible and deformable tubing, such as PVC tubing which is sealingly compressed by the front and rear walls when they are assembled and defines in combination with the planar walls, at least one working cavity having a working cavity volume. The volume and/or volumes is/are variable and a function of the placement of and the dimensions, the length and the OD, of the tubing and the area of the planar walls. The tubing may also be compressed by the weight and resultant pressure on the tubing from any fluid materials, including liquids, which may be introduced into the working cavity or cavities to further provide for a seal. There is also provided various devices, such as stands, fastening means, means for changing the degree of transparency of the planar walls toward opacity all of which are provided in order to better facilitate the use and enhance the usefulness of the teaching tank. There is also a kit of components including the front and rear walls made preferably of rigid transparent plastic material, a supply of flexible plastic or rubber or synthetic tubing having a predetermined OD or having different OD's to be made into selected lengths and to be used to create the tank cavities, bolts or other fasteners and spacers for holding the front and rear walls in parallel opposed and predetermined spaced relationship to form the tank volume, tank support stand, and an instruction book including experiments that are performable using the teaching tank and experimental components and materials which may be included with the kit. The tank is simple, low cost, convenient to use, excellent visual clarity and distant observation, low volume and has versatility as to types of experiments which can be performed with excellent group observation potential. The very use of the teaching tank creates an educational advantage for the teacher and the student in that teachers are afforded a more exciting and visual way to demonstrate a principle of science and the student observers are provided with the opportunity to observe demonstrations and to safely perform experiments wherein the phenomena taking place is more accurately observed or observable and thus perhaps better understood.
