The players are in a circle. One begins and picks any object from the air. He holds it in a certain way and presents it to his neighbour as a gift. The neighbour is happy about it, defines what the gift is and thanks. Then he puts the gift away and picks a new gift from the air, etc.
Example:
*A picks an oblong object and hands it over to B:"Here, I give you this."
*B:"Ui, great! A machine gun! I've always wanted that! Thank you!"
*B puts down the machine gun and picks a heavy, melon-sized object:"Here's a present for you!"
*C:"Oh, wow, a bowling ball! Great!" and so on.
So one player makes a gestural default and the other player defines what it is. (As always applies: take the first association, don't try to be original.) The surplus must, of course, immediately accept the recipient's verbal offer (even if he or she thought of a completely different object). The two can, if they want, also change 1 to 2 friendly sentences with each other, e. g. highlighting the special features of the gift, for which they may need it, or similar.
Tip:
You can imagine an imaginary tree whose branches hold the presents. The size, shape, etc. of the gifts must of course be as varied as possible.
