In general, men should drink around 13 cups of water and other fluids daily (about 3 liters), and women should aim for 9 cups (2.2 liters). You can stick to the daily recommended amount of water during your water fast. Choose the purest water you can, or drink distilled water.  Don’t drink all that water at once! Spread out your water consumption throughout the day. Try setting out three 1-liter jugs every day, so you can see how much water you should drink. Don’t drink more water than the recommended amount, as this can throw off the balance of salt and minerals in your body and cause health problems. If you get strong hunger pangs, work through it by drinking 1-2 glasses of water. Then lie down and rest. The craving will usually pass. You can also try distracting yourself by reading or meditating. Break your fast with orange or lemon juice first. Then proceed to add foods to your diet gradually. Eat small amounts about every 2 hours, at first. Proceed in a stepwise process from easily digested foods to foods that are harder to digest. Depending on the length of your fast, you can spread this process out over one day or many days:  Fruit juice Vegetable juice Raw fruit and green leafy vegetables Yogurt Vegetable soup and cooked vegetables Cooked grains and beans Milk, dairy, and eggs Meat, fish, and poultry Everything else Fasting won’t help your health much if you return to eating high-fat and high-sugar foods afterwards. Follow a diet high in fruits, vegetables, and whole grains, and low in bad fats and refined sugar. Exercise for 30 minutes five days a week. Live a healthy lifestyle to improve your health and wellbeing, and let fasting be only a small part of that.

Petroleum jelly is a fun ink to use because it will glow in the dark under a black light (UV light). To use this type of invisible ink, you will need petroleum jelly, Q-tip cotton swabs, white computer paper, and a black light.  Most of these materials should be easily found around the house. You can purchase a black light at a local superstore or online. Dip the cotton swab into the petroleum jelly until you have a small amount on the end. You don’t want a big glob of it because that will be difficult to write with. Write your message with the tip of the cotton swab. For best results, try to make the writing smooth, avoiding bumps from the jelly. To reveal the written message, shine a black light on the paper. You can even turn the normal lights out or look at it in a dark closet. The words you wrote will glow in the dark under the black light. You don’t have to wait for the jelly to dry completely before revealing the message.
