This is a deluxe version of possibly Magiro’s finest hour: Hydro Die. It was created in a limited edition of 15 in Germany I was told. You place the submarine clearly in the bottom of the container, fill it with water, say the magic words and it disappears with out trace. Works really well and large enough to be seen in a parlor setting but it could be performed in a formal close-up setting (assuming you could find the water).
