Magic Tricks

Pros: It's a versatile sleight of hand effect that can translate over to crayons, pens, markers, etc. Pretty simple to do as well.

Cons: Needs to be done at a table so standing and moving around isn't an option. A little bit of setup is needed before hand as well making this not 100% impromptu as I had hoped. The teaching isn't very good quality.

Overall, Mario Lopez is a brilliant thinker that has put out an effect that can definitely work. It's simple but flows nicely. The teaching can use a bit of work but all in all I recommend this effect to any sleight of hand worker or anyone that is interested in learning sleights.
