Well, that kid is never touching a pressure washer again.
To Infinity And Beyond!: Little Kid Versus Pressure Washer Surface Cleaner

This is a short video of a dad giving his son the Superman test by handing him a pressure washer with a surface cleaning attachment and seeing if he’s got the strength to hold it down. He does not. Man, I can’t even see a pressure washer without painfully recalling the time I used one to clean my uncle’s basement with absolutely zero ventilation, siphoning pure bleach from the bottle until my eyes bled and every breath felt like a murder hornet sting to the lungs. “What doesn’t kill you makes you stronger, right?” I have chronic respiratory issues now.
