How to change money substantially?

Show the audience the twenty coppers in your hand. They are all ordinary copper coins. Blow it and it becomes money. Put it on the table, put it away, tidy it up and put it on the table (pictured). Two or three coins turned over, all gold. Literal space from the back, then put it in your hand. Blow a breath, suddenly turned into five-color copper coins. In turn, it is distributed in the palm of your hand, and once again, it is still the original copper coin.

Description:

Use 20 bills of the same color, with gold foil first. They are pasted with four pieces of double-sided stickers and sixteen pieces of single-sided stickers (eight pieces are literal and eight pieces are back). After pasting, leave six of the sixteen (three are literally three on the back), and the remaining ten are painted in five colors (the side without gold foil is painted in five colors). Yes, stack twenty dollars together (the method of stacking is word by word), and the bottom is half copper and half gold (the side that picks half copper has words, and the side that picks half copper should face down). Fold four more on it, and both sides are gold. Put five pieces of half copper and half gold on it (half copper face up). After folding, put it on with a rope like this. When changing, hold the copper coin in your hand as usual (half copper face is positive). This just untied the rope (for the audience to see, the top and bottom are copper). Move the bottom copper coin to the top (you need to turn it upside down so that half of the copper coin faces up), put five copper coins on the table (all copper coins), pick them up and put them back in their original positions, and blow on the copper coins, that is, put stacks of copper coins together, so that half of their gold faces are exposed. Then, put the cloth on the table (divided into five rows with four pieces in each row) and arrange it from left to right (if the text and the back are separated, they are all gold).

When you play it again, you should put it from bottom to top. Every time you put it away, take one (that is, five pieces) as a stack, turn it upside down and put it on the table (after this episode), divide it into four stacks, and then arrange it one after another (each stack is arranged as a horizontal bar). When folding, the words are up in five rows, and when folding, the back is up in five rows (so it is obvious that twenty coppers are gold on both sides). The arrangement is still from left to right. When you put it away, you collect it from the bottom up (don't fold it sporadically), but one by one from the bottom up, put twenty copper coins together and put them in your hand. At this time, move the six copper coins on the top to the bottom, take a breath and fold the copper coins on the palm of your hand. In this way, the copper coins on the surface are five-color coins. Pick them one by one and arrange them in the palm of your hand. Then fold it up as it is, and move the bottom six copper coins to the top, still copper coins. After playing, move the dollar above (semi-copper, with words on it) to the bottom and put it on with a rope (from top to bottom, it's all copper, with a back on it and words on it).
