apple juice works just as good as cider and is cheaper
sprite works nice too,adds a sweet taste to the puff
you could always put like lemon juice in the well,citrusy is a good change up now and then.
green tea gives a nice earthly refreshing hit,but make sure the gtea is cold
yes i done these aswell as many more. im not a fan of bongs but heres a few that i do use that makes me a mediocre fan of bongs
