Saw this awesome pic of a pink sparkly bong. I wanted it so bad bit couldn't find anything close to it online or in shops. So I made one myself, It's so easy! here's how: Get a clear glass bong Get your preferred color of sparkle Get some mod podge Spread 1 coat of mod on the bong. Pour out sparkle on top. I did this over a piece of paper so I could pour fallen sparkle back in It's container. I did 2 coats. Let it dry for a few hours and you're set!
At first it left them on my mouth, but if you coat it in mod podge it'll seal it in. Maybe 2 coats of mod posher and wiping it down after would help. A few sparkles fall off occasionally but It's nothing bad. Definitely worth it.
