Hello, I'm 49TL. An edit that you recently made to Carbon-14 seemed to be a test and has been removed. If you want more 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! 49 TL  20:37, 24 February 2019 (UTC)
