you don’t sound douchey, it’s okay to ask questions no worries. they’re called 2k Diffuser Beads and theyre for added percolation. they break up the smoke bubbles to give you a smoother hit. they’re made of thick durable plastic so they can be cleaned with alcohol and salt just like your pieces. you can order them off Amazon or grasscity and they have a website too but I dunno if they sell them there. for straight tubes I recommend purchasing a bag, for beaker bongs I recommend purchasing a whole jar. in order to change the water, I pour my bong over a strainer so the beads don’t fall down the drain. I suggest designating a specific strainer for your beads tho cos it will get covered in resin with repeated use. also if you want to, you can use a funnel to easily pour the beads into your bong. this is what I do to prevent beads from flying everywhere haha cos I can be a little clumsy while stoned haha I hope this helped I tried to be as informative as possible!
