Social activities between games in an off season event

[RandomStyuff]

Hi,
I'm the organizer of Project Falafel- An Israeli version of OCCRA or Bunnybots.
This year is our pilot, and therefore we have only 5 teams on board.
In a 2v2 game, that means teams are constantly getting on and off the field, and if they need repairs, we don't have other teams to fill in. This, paired with the historic communications problems with Israel which will no-doubtingly affect us, force us to estimate a 10 minute turn around time from start of one game to the start of another, which means nearly 7 minutes of dead time in between games.
An idea came up to try and fill those periods of time with social activities. Something that people would enjoy. If possible we want to help get more social connection between the teams too. Does anyone have any ideas for activities or anything we can do to fill this dead time? We will have between 12-15 games to fill, so any ideas, no matter how crazy might work!

(What I have so far:
* I'm going to try to get a band to come and play, which could be nice for 2-3 breaks
*I had a general concept of making something along the lines of a gameshow, but it does feel a little cheasy)

So, any ideas?
