styling curtain bangs with no heat

hello everybody. in a few weeks i'll be leaving for summer camp for two weeks and we are not allowed to have any irons or hair dryers therefore it is hard for me to style my curtain bangs as when naturally dried they sit weirdly on my face. i'm used to kind of strengthening them to look better but now i do not really have that option. i don't have a specific hair routine other than applying a hair mask when showering sometimes and a curling mousse. do you have any tips on how to style them with no heat while also being kind of easy to do?
