Entertaining a 2 year old is not complex.
Dish soap, dish pan (we do not have stopper for our garbage disposal) and water.
Throw in a cup and a bowl.
This kept her busy for easily 30 minutes. Even though I wanted to be right there since she was standing on a chair. I was able to make lunch, clean up the counters, and start a load of laundry (which is right there in the kitchen).
