15. Unblock Drains
A blocked drain is the worst. However, you probably remember science projects from school, where you mixed vinegar and baking soda to create erupting volcanoes. It turns out that the same chemical reaction unblocks drains, too!
16. No Smelly Garbage Disposal
Your garbage disposal is probably the best invention ever. It makes cleanup that much easier, but all that food waste creates a bad smell. Remedy that by washing it out with water and adding baking soda with a touch of water. After about 10 minutes, pour some vinegar down there and rinse it away!
