We always hear about the National Magic Water Cups and how 3 empty glasses are produced at the climax and then final surprise when you pour water from the cups to the 3 empty glasses but we never saw anyone performing it. I have a set of National Magic Water Cups, and I tried to do it and tape it for youtube but my cups kept leaking water during the routine with cups and balls moves. I might have an old set and it is not perfect, or I am doing it wrong and that why it keeps leaking.

Here is a suggestion, If anyone has a set, can you try it and see if it works for you and tape it for youtube, as this is going to be a first and it will bring you good publicity since there is not any recorded video of performing The National Magic Water Cups.

Actually, the correct name for these is the National Miracle Cups and Balls. They were available in at least three different sizes.

Do you have the original instructions for these? If you don't, then let me know, and I'll send them to you. The liquid in the cups must be at room temperature or the cups will sweat.

There is a video of a British performer using these on YouTube. You won't find it by searching for "National Water Cups," though. I don't know who it was, but if you search for cups and balls and add England to the search term you may find it.

They were not very practical cups.
