This reminds me of one of the funniest things I’ve seen in my life. We were hanging out at a beach with Tech friends. The grandfather was hugely wealthy from inventing some sort of organic chemistry process. The grandkids, who were about 21, were complaining that the 55k gallon pool was too hot (beachside pool on HHI in August). One of the geniuses goes and fills a 64 oz cup with ice and throws it in the pool. Then they all marvel because it didn’t cool the pool down. You could see the disgust on the grandfather’s face. He just shook his head and walked inside. I can only assume it was to go slap his wife.
