A one-on-one challenge involving hands turn into lightsabers.
Players find a partner. The two players each form a gun ("L shape") out of their hand and grab the hand of their partner (index finger is outstretched for each).
When the facilitator says go, each person tries to touch the other person's body with their outstretched index finger.
The winner is whichever person first tags the other.
For larger groups, this game can be played as a round-based elimination game (all the winners play other winners), until there is only one player left.
