Everything seemed great until 15 min or so later i noticed foam flowing out of the airlock. I pulled the airlock out and set it in the shower and it's been overflowing for about an hour now. I assume the sugar from the pineapple is creating carbonation and I'm hoping I can just let it go until it stops and put the airlock back on and resume the procedure. Any advice would be much appreciated.
During fermentation your beer gets saturated with all the CO2 it can handle at that temperature. When you add things like hops or fruit, it provides nucleation sites for CO2 to bubble out of solution. That's all. The sooner you get the airlock on, the better. But until then, you're all good.
