Bath toy with thermally erasable drawing surface

A thermally erasable bath toy for enabling a user to create and erase drawing figures in a wet environment, the bath toy comprising:

• a drawing desk;
• a drawing surface disposed on the drawing desk;
• and
• a thermochromic material disposed over at least a portion of the drawing surface wherein the thermochromic material has an active temperature range wherein the thermochromic material will demonstrate a change in color at least from a first color to a second color;
• a temperature-operated drawing implement of heat transmissible material for selectively inducing the thermochromic material to enter its active temperature range wherein the drawing implement comprises a temperature applicator for being brought into a given temperature condition and for being applied to the thermochromic material on the drawing surface to induce the thermochromic material to enter its active temperature range wherein the temperature applicator has a body portion and a drawing tip and wherein the drawing implement further comprises a handle portion for retaining the body portion of the temperature applicator wherein the handle portion has a distal end adjacent to the drawing tip of the temperature applicator and a proximal end, wherein the handle portion comprises a volume of insulative material surrounding the body portion of the temperature applicator but leaving the drawing tip of the temperature applicator exposed, and wherein the body portion of the temperature applicator comprises an elongate shaft with a distal end comprising the drawing tip, a proximal end, and an enlarged weight portion disposed adjacent to the proximal end of the elongate shaft whereby the elongate shaft functions as a skeleton structure for the volume of insulative material;
• whereby a user can induce a change in color in the thermochromic material at least from a first color to a second color by inducing the thermochromic material to enter its active temperature range so that a user can create drawing figures on the drawing surface and whereby the thermochromic material will exhibit a change in color at least from the second color back to the first color as the thermochromic material leaves its active temperature range whereby the drawing figures can be erased from the drawing surface.
