Hello, I'm Pickersgill-Cunliffe. I wanted to let you know that I reverted one of your recent contributions—specifically this edit to Brian Busby—because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Teahouse or the Help desk. Thanks.

Please refrain from making test edits in Wikipedia pages, such as those you made to Conservation of mass, even if you intend to fix them later. Your edits have been reverted. If you would like to experiment again, please use the sandbox. Thank you. Din oz1  (chat?) (he/him) 12:57, 26 March 2024 (UTC)
