Beer Bubbler / Yeast Starter

thingiverse

I recently decided to start brewing my own beer, so I'm making my own yeast and building this bubbler to share with you. You can adjust the item scale based on your container, and add a small screw to the hole to keep it from shifting. To ensure a tight seal, use some plastic film as a gasket. Fill the tube with a small amount of water (I used a syringe or pipette).
