using glow stick fluid outside the stick help
alright need some help. im wanting to fill a bunch of test tubes with the fluid from glow sticks for my halloween costume this year. but for some reason after removing the fluid from the glow sticks and putting it in the tubes it does not stay lit for very long at all. im talking anywhere from 3-4 mins to 60 seconds. i have tried breaking the inner container before and after putting it into the test tube, and for some reason mixing the two after seems to have a longer life. moving and shaking the test tubes does cause the mix to glow for less time and im going to be wearing them so i cant have this. does any one have any kind of knowledge if this area? i could really use your help. any ideas on how to fix the life span?
