This is a solid resource. Make no mistake, it covers a ridiculous amount of content. It's begins
simply and moves methodically to more advanced material. It covers everything you need to know about
Cups & Balls (and even magic wands! Which was a weird inclusion). My suggestion would be to get a
resource like this and then invest in Table Hopping Cups and Balls. Buy now if you are interested in
more than just cards and sponge balls :)
