i promised my friend a rainbow in a bottle and i was wondering how i could make that happen. i tried using mirrors but i cant seem to make it. is there anyway i can make a noticeable rainbow in a bottle? if so how? i know its a strange question but i feel a physcisist might be able to help me get a start
