I don't have a slide for my bong atm (old one broke), but it's 2am and i'm feelin' some bong rips. Been smoking bowls out of my pipe but i want a smooth hit with some ice. So, my question is how would i go about constructing a makeshift slide? Just for the time being until i get around to going to the headshop. I was thinking about something involving tinfoil? and maybe a pen?
