The heat-activated fish cups and coasters will keep guests entertained until the host can finish wrapping up some treats in the kitchen.

According to Inno.Park, the creators of the heat-activated fish cups and coasters reveal swimming school of goldfish at 68 degrees Celsius. Moments after the adorable glass cup, which have handles shaped like waving hands, are placed onto the triangular coasters, a miniature goldfish appears in the black sea. The mug doesn't necessarily have to be placed in the center of the triangle to work. Schools of fish that bridge two mug mats can be created by placing them alongside each other, creating an image of swimming fish. Although the coasters are activated at 68 Celsius, it has the ability to withstand a range of -20 to 80 degrees Celsius.
