I was thinking -- let's reinact the Battle For Earth using water guns. We could build Kilrathi & ConFederation battlewagons out of cardboard armor & plastic shielding and mount water gun turrets on them. We could also build those "Milk Jug Rafts" depicted in advertisements and mount our wagons on them to make our reinactment more naval like. We could have remote controlled model fighters equipped with those $1 water gun pistols too and remote controlled model bombers equipped with 2" balloons to represent torpedoes. We could have our battlewagons mount larger water balloon launchers to represent the capital ship torpedoes as well.
