ESL Beer Pong!!

I recently came across a cool drinking came called "Beer Pong" and decided to adapt it to ESL.  A little searching on the internet and I found an ESL teacher in Korea who'd already used the idea as a final day activity at her middle school.  Taking what she'd done and developing it a little further, here are the basic rules.

1. Set up 6 cups at either end of a long table (see diagram)
2. One student from either team stands at either end (or students can line up).
3. First student to answer a grammar/vocab question goes first (or you can just flip a coin, janken etc...)
4. Let's say Team A goes first.  Team A's student throws the pingpong ball from their end into their opponents cup.  If it goes in, that cup from the other team is removed, and they are the winner.  If it does not, the other team has a go and so on.
5. Each player has five attempts to get their ball in their opponents cups, and each takes turns to throw into their opponents cups.  Students replace each other until all their opponents cups have been eliminated.  The winning team is the one who manages to clear the other's cup before theirs are.
6. Each time, students can answer grammar questions to help practice the vocabulary or you could just play for fun! :)

Notes:
i)  Since Beer Pong relies on beer in the bottom of each cup to hold it down, I recommend using a little blutak on the bottom of each cup to prevent them all scattering on each round.
ii) You could write forfeits on the bottom of each cup for the other team to perform each time you score one of their cups.  You could also role a dice to determine how many times they have to do the forfeit.
iii) You could even write grammar or words on the bottom of each cup for the opposing team to make sentences with each time one team scores a point.  There are loads of variations.
