Hello, I'm Spinningspark. An edit that you recently made to Passivity (engineering) seemed to be a test and has been removed. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! SpinningSpark 14:56, 1 September 2019 (UTC)
