Standing Broom

A broom stands alone. Silently. Eeerily. Mysteriously. Amaze the grandkids with your magical skills.

You need:
A broom. Most any broom will work, you won't know until you try it.
A floor.  

Take the broom handle in one hand and stand the broom up on it's bristles. Fiddle with it 'till it stays standing up. Practice makes perfect, it is a learned skill.
