How do you prevent herb from falling into bong water without a screen ? The glass built in screens not working .. This style almost I’ll add pic eventually Dual Use 14.5mm / 18.8mm Bowl with Handle | Grasscity.com
You can get a regular bowl and use a glass daisy screen. That pretty much ensures no weed gets sucked through but it comes at the cost of airflow, and they res up quick which makes the airflow even worse, they can get stuck too and just generally be a bit of a pain in the ass but overall they're worth having imo.
