Cereal Brainwave by Tri City Magic

NOTE:  This is new. 
It came from a magician's estate.  

Cereal Brainwave is just like the original Brainwave effect, but with cereal boxes on the faces!

The magician shows eight cards with cereal boxes on the faces. The spectator chooses a card which is set down on the table face up. All the remaining cards are shown to have red backs except for the spectator’s card which is blue! This can then be instantly repeated and the spectator’s card could be a red back and all the other cards are blue.

Don't repeat this for the same person. Table to table is a great way to do it.

Specially printed cards with a link to video instructions!

If you already do the Nick Trost Brainwave then you know how this one works.  8 boxes of cereal on the faces - 4 of the cards have a blue back and 4 have a red back this is a great update on the original eight card brainwave that just used regular playing cards.  Now you can do it with Popular Cereal Box designed cards.
