Konapun is a Japanese toy that was produced by Bandai between 2007 and 2009. It allowed children to cook what convincingly appears to be food, but is not actually edible:
The toy goes to amazing lengths to make it look and feel like a realistic cooking process. So for example, if you are making something fried like donuts you drop the "donuts" into fake "oil" and it bubbles as if it was really frying. This bubbling/frying effect is used in several Konapun toys such as the hamburger grill and one that makes tempura.
It's astounding how real each of the food items look in the end. For example, the rice separates into tiny clumps that look just like sticky rice. And the marinara sauce on the spaghetti is runny and looks just like real sauce. Couple that with the kits' tiny mixing bowls, spatulas, cookie cutters, and other tools, and it makes for a fascinating toy.
