I have a piece of paper with confidential information on it that I need to permanently destroy so it can never be reconstructed. This means that I can't just tear the paper manually, since with lots of work, someone could put the torn pieces together like a puzzle. I do not have access to a shredder, and it's not possible for me to leave my home to use one elsewhere. I tried putting the paper in a bath of water and detergent, but the ink does not come off the paper, so the confidential information is still visible. I cannot burn the paper, since that might set off the fire alarm in my building.

I only have access to household items, and I don't have any bleach. How am I supposed to destroy the information on this paper?
I'm afraid the best option you have is burning it. To prevent setting the fire alarm off, try holding it out of a window as it burns
