The most classic and amusing "running gag": THE INEXHAURABLE VASE. The magician takes a vessel full of water and after emptying it to the last drop, sets it aside and presents other effects. The vase is immediately taken up again and more water comes out of it. The same operation is repeated several times during the show. This item has a very common shape, you can hold the vase with flowers in it, seemingly just to better adorn the scene, then take the flowers out and perform the effect. Your audience won't stop laughing!
The vase is 20 cm high. Aluminum material.
