Glue-sniffing gag

Hi everyone! I was wondering if anyone has any experience/tips for doing a "sniffing glue" gag? Supposed to be a small bottle/tube of it (not quite a dramatic Charlie Kelly thing), and I want to make sure I can do it safely. Was thinking of cutting one and cleaning it best I can, but if anyone knows has ever done this before, I'd really love some pointers! Thanks so much! <3 Dani Hilzenrath
