Abstract
A color changing water toy generally includes a porous absorbent core that absorbs water, typically made from a soft open cell foam. The porous core is covered with colorful graphics, at least some of which are printed with thermochromically sensitive paint or dye. The absorbent core is preferably covered with a porous skin typically made with fabric that has been printed with the colorful graphics. At least some of the graphics are printed with thermochromically sensitive paint or dye. Thus, the color changing water toy absorbs water that is readily released upon the water toy striking an object and also changes color depending upon the temperature of its environment.
Claims20
A temperature sensitive color changing water toy, comprising:
- a soft, porous, liquid absorbent core whereby the toy may absorb and releasably retain a quantity of liquid;
- and
- a thermochromically sensitive material operably associated with an exterior surface of the toy such that the water toy changes color in response to the temperature of its environment.
A temperature sensitive color changing water toy, comprising:
- a soft, porous, liquid absorbent open cell foam core whereby the toy may absorb and releasably retain a quantity of water;
- a flexible porous fabric substantially covering said core;
- a thermochromically sensitive material screen printed on said fabric covering whereby the water toy changes color in response to the temperature of its environment.
A method for manufacturing a temperature sensitive color changing water toy, comprising the steps of:
- forming a soft porous liquid absorbent core;
- printing a thin flexible outer shell material with thermochromic material in a graphical pattern;
- applying said outer shell material to at least a portion of an exterior of said core.
A temperature sensitive color changing water toy, comprising:
- means for absorbing and releasably retaining a quantity of liquid;
- and
- means for changing the color of a surface of said toy in response to environmental temperature.
