Dip one toothpick in liquid dishwashing soap before you have an audience. Make sure no one else sees you do this part--it's the "magic" in the trick.
Clean a shallow pan, or pie plate. Rinse thoroughly. Make sure there is no soap residue left in the pan. Fill the pan with water, and set it on a table or hard surface where it won't spill.
Bring your audience in at this point. Have them sit around a table. If the event is being recorded, bring the camera in for a close shot.
Arrange the other five toothpicks (none have soap on them) in a pentagon shape on top of the water in the pan. The toothpicks should overlap a little so they stay together.
Wave the sixth, soap-dipped toothpick around in the air and say some magical words like "Alacazam," or something inspired that you make up.
Stick the toothpick into the water in the middle of the pentagon, and watch as the other five toothpicks scatter away.
