DUH! Dats a tough one. First you have to call the FBI and the EPA to investigate. Allow approximately 3 to 6 years for a semi comprehensible answer. Once this has been done a government agency consisting of out of work hacks needs to be established to study the best method for extracting the currency. Having spent several years and 20 billion dollars in an unsuccessful quest for an answer a second agency consisting of Engineering consultants should be called in. Cost for this should be relatively low since most of the leg work has already been done. Less than one billion dollars give or take. At this point a hazmat team will be required to wipe up the spill. But not until the responsible party has been established and a super fund has been allocated. If all else fails simply call in the IRS and tell them there are taxes due on it from 12 years ago they'll turn it into a $400 dollar bill.
the trick it to lift the glass slightly, water will fill the dish but don't lift the glass above the dish. reach under with a pen or something and remove the money.
