B’Wave is a 4-card packet card trick popularized by Max Maven.  In this effect, a packet of 4 Kings is placed face downwards to one side on a table.  A suit is freely called out by a spectator.  The King of the chosen suit is the only King that is shown to be face upwards from the packet of 4 cards.  The other 3 cards are then shown not to be the other 3 Kings, but all blank cards!

Nitrate is backwards B’Wave.  In effect, the King of the chosen suit is the only card shown to be facing upwards from a packet of 4 cards.  The other cards are shown to be blank cards.  The King of the chosen suit is taken out of the packet and placed face downwards onto the spectator’s hand.  When the spectator turns over this card, it becomes blank.  The other 3 blank cards are now shown to be the other 3 Kings!

There are a lot of magic taking place, but only 4 cards are used.  You do need to know how to perform some basic card sleights, in particular, the Elmsley and frustration counts.

You are supplied with the 4 special cards inside a nice small silver envelope.  The cards are all in bicycle backs.  A video instructions is available for download from the internet.  The video has Cameron Francis explaining how to perform the effect.  He also teaches you all the sleights needed to perform Nitrate, including some variations such as the Rumba and Kiss Counts.

You are also supplied with a small but nicely printed accordion-folded sheet of instructions.  However, they do not include descriptions of how to perform the various sleights.  For these, you have to refer to the video.  The Ruma and the Kiss Counts are really nice slights for you to use as an alternative to the frustration count.

B‘Wave becomes a hit because of its interesting plot.  Backward B’Wave has an equally captivating plot, and Nitrate will certainly become popular with magicians.

If you like card tricks with a lot of magic happening that uses only 4 cards, and does not involve carrying a full deck of cards, Nitrate is right down your alley.  (9/10 star rating)
