Players sit in a circle facing the center. The backpack is placed in the center of the circle.
The first player states their name and puts an imaginary object starting with the same letter as their name in the backpack (i.e. Ben puts in "beef jerkey"; Sam puts in "smoothies").
The next player tells everyone what all the preceding players have put in their bag, and then what they put in the bag (so that the final person who goes must list everyone's name and object).
