It really is a nice visual and I have a good reason for the three star rating. At the end you must
Palm and ditch a skinny tube that's like three or four inches long. Also as the quick change happens
there is also a quick noise. You can be creative to disguise the noise. Yes you can change any
dollar to any currency.
What is your "good reason" for only 3 stars? The fact that the effect requires some skill or practice? Some assembly required? Not entirely self working? (Not that any of these should result in a lost star but merely a caveat). Also, there's no need to tip the method in a review. The video itself is helpful enough to point the way towards method. No reason to encourage piracy.
