Jay Sankey is doing work with these trick tutorial videos. In this latest effort, he shows us how to make a marked elastic band disappear and reappear inside of a tuck box, and how to pull an elastic band through a pencil. The tuck box trick is quick and relatively low-key, but with the right set up it could land really well. The pencil trick is a lightning fast sleight that really pops close up, do it with a borrowed pencil for maximum impact.
