"Skinja-Beer" (Ginger Ale)

1.5 liter warm water
Juice of one orange
1 plastic 1.5 liter bottle
4-6 Tbsp sugar
1 Tbsp ginger
10 cloves
1 tsp dry yeast

Mix everything in the plastic bottle and let sit in a warm place for about 8-12hrs. You will know its ready when the plastic bottle is taut from the carbonation like soda from the store (the carbonation doesn't last long though). Then put it in the fridge to chill.

Try replacing water with watermelon juice, but don't let it sit too long or you'll have alcohol.
