Article: Dump the baking soda directly into the water. Try to spread it evenly throughout the bowl so it covers all of the surfaces. Wait until the baking soda sinks to the bottom of the toilet before moving on. Slowly pour the vinegar into your toilet. Work in a circular pattern so the vinegar evenly distributes throughout the bowl. As it mixes with the baking soda, it will start to fizz and bubble due to a chemical reaction. Make sure not to add the vinegar so fast that the fizz goes over the edge of your toilet or else you'll have a bigger mess to clean up. As the vinegar and baking soda react, they'll break down the clog so it can fit through your pipes more easily. Use another bathroom or wait until 1 hour has passed before trying to flush it. If the water still doesn't go down, try adding the same amount of baking soda and vinegar, but let it sit overnight.

This exercise is best done when standing. Hold the barbell or dumbbells with a palm-forward grip, slightly wider than your shoulders. Hold the weight in front of your head, just above shoulder level. You can do this exercise while seated, although the seated version does not exercise your core as much. If you've had lower back trouble, stick to the seated version. Sit on a press bench with vertical support for your back. Keep your back straight and your feet firmly planted on the ground. Shoulder presses build muscle most efficiently as a high-weight, low-repetition activity. Begin with 2-4 sets of 4-8 reps each.
