Hello, I'm Jim1138. An edit you recently made to Negative thermal expansion seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Jim1138 (talk) 08:20, 25 August 2018 (UTC)
