I didn't actually break it myself but it was my fault. I set the hydrometer down after taking an OG reading and forgot about it. The next day my 3 year old saw it and wanted to help me clean up, when she tried to pick it up it snapped in half, the wort had dried and glued it to the table. She almost started crying thinking it was her fault. but I assured her it was an accident.
239 + 1= 240
