Have a rewarding running trick!
Similar to a running gag in a comedy show a running trick is a trick is about repetition. There are two main ways of doing it. The first one is to attempt a certain trick over and over again, but failing. The Second one is to repeat a minor trick over and over until it becomes increasingly better and better.
Both ways need a rewarding finish. All this interluding stuff needs to add up to something.
Here is an example for the first way. You declare to perform the famous cut and restored rope. You show the rope, you cut it and then comment "This is the easy part. The next part.... well I'm working on it." Then you toss the ropes in a bag next to you.
Later you get out another piece of rope and cut it, this time you do a knot to get them back together and toss the bundle in the bag.
A few tricks later you attempt it again, Cut the rope, it is then visually restored but just as you take your applause the rope breaks again. You toss the pieces in the bag.
And finally you attempt it again, you cut and restore the rope. Being confident you take the bag, rip it open and from it all the pieces have become one long rope. Knowing the magic apparatus out there will make you understand that this routine is a self worker.
Here is an example for the second way. You borrow a 10 dollar note from one spectator and then another 10 dollar note from another spectator. Fold both together, then unfold, both have fused into a 20 dollar bill. So far the setup.... now you show two little bags, one red, the other one blue. "I'm gonna place the bill into one of the bags, then the first guy gets to guess where the bill is. If he's right, he gets to keep the bill. If he's wrong the game continues." Of course the spectator guesses wrong.
You do your next trick and after that you come back to the bills. "Now it's the second guys turn, red or blue? It was in the red one, maybe I put it there again, but I wouldn't be so stupid would I?" So he guesses and is wrong.... This can go on an on. Now for the finish.... "I'll make it easier." Now the twenty is openly placed into the blue bag. "You both get to choose. You can either trust me and take the blue bag or mistrust me and choose the red one. But whatever you get, the other guy gets the other bag." The choice is made and both open their bags at the same time. Both find nothing but their 10 dollar notes. Methodwise a TT gets your far ahead.
A running trick doesn't connect the tricks, but gives the impression to do so. It creates the illusion of a well thought out show. Try it, if you have nothing else.
