    hello i wanted to ask the public of what when wrong. if you have any answers please comment back to me. my name is Oliver, my daughters boyfriend had an exploding time a little while ago. he wanted to clean his pennies so he went online and looked up a way to clean them. he then proceeded to place the pennies in a jar with salt and vinegar, then he placed a lid on the jar. about 2 hours later there was a sever explosion, glass shards filled the whole room, some of them embedded into the walls 15 feet away and others into the ceiling about 10 feet up. there is also an indent in the ceiling where the lid hit. please let me know if you know what went wrong.

    I will guess that the mixture with copper (cleaning) and a lid on the jar trapped the gas and it combusted. Next time just try coca cola.
