One of my favorite tricks that I did last month in my school assembly show is my Take Out Box. This is a utility box that I created that can make items appear, disappear or change. In the show I used it to make a Tennis Ball Appear.
Here’s it in action:
What I like about this is that it’s a magic box that’s a normal box…well by normal I mean something that people have seen before. It’s also handheld, so you don’t need a table. Personally I’m anti-tricks that happen on a table in stage/parlor shows as the table puts a barrier between you and the audience. The table also limits the sight lines of what can be seen. The exception would be if you’re using projection.
The extra bonus is that the box is versatile. It has more than one use, unlike many other stage magic props.
