Science is cool, right? Clean a slow drain with baking soda and vinegar, and it makes things smell better but it doesn't do much for getting rid of the unwanted matter blocking your pipes. So instead try a little instant yeast. To which you say, I'm sorry, what?If your shower or bathroom sink is running a little slow, it's been said you can pour two packets (or a few tablespoons) of instant yeast down your drain. Follow that with a tablespoon of cane sugar and then 1 cup of water. Let it sit for 15 minutes (just like you would if you were baking) so the yeast can wake up and start eating the sugar and then turn your water on fully for a few moments to rinse it down.
