This is not a stage trick.
Its either close up or parlor.
and if you are going to use it as a stage trick,
Shoot yourself in the head, or the audience will.
wow a bit harsh their he just has it in the wrong section. But earplugs are fine I used them in the last ibm convention one of the dealers let me do my routine with them. They have a lot of qualities that are nice like the sit flat, they are smaller in your pocket. ect but personally i am a fan of the classics so i stick with regular sponges and my routine uses mini sponges so i pretty much need the little red balls. but if you are new to sponge magic earplugs are a good start. If you like it get some sponge bunnys, and regular sponge balls.
