A very popular- and VERY EASY trick! Comes with an egg- but you can use other things, too!
And the mesh cover lets you see the object INSTANTLY as it appears and disappears!
The basic routine goes like this:
Show the bag to your spectators.
Place your hand inside the bag- your audience can see your hand through the net, and can see that there is nothing else inside the bag.
At your command, an egg (or sponge ball or small stuffed animal- or a handful of candy) INSTANTLY appears in the bag!
Next, you can appear to take the item out of the bag.
The bag looks empty.
But suddenly, another egg appears inside the bag!
Simple? IT SURE IS!
And the routine can be as short or long as you'd like.
