My middle son, recently potty-trained, stood at the toilet of our newly cleaned bathroom.   I stood beside him and coached him to hit the water.   He tried so hard, but inevitably, he hit that narrow space between the tank and the toilet base like a bull’s-eye.   I jumped, startling him, and it went everywhere!  Another day of cleaning for mom.   But, it wasn’t the first time this happened.  We’d been at this for a couple months.  It was just the first time I said, “There’s gotta be a better way!”   I spent the next 2 hours drawing up my invention.
