While travelling, hide your money in an empty chapstick tube

If you travel a lot, you might want to be careful where you place your money. One of my friends was pick-pocketed in Paris, and his money belt seemed to be easy prey for thieves. Why not stash emergency money in a place criminals would never suspect? Hide a few rolled-up dollars in an empty chapstick tube, something small and easily hidden in a jacket pocket, for instance. The tube might not be able to fit more than a few 20s, but it should be for emergency money as opposed to daily spending cash. See the attached pic for an overview of how to roll up the bills.
