Method:

Equipment

• ginger
• disposable cup
• water
• teaspoon and tablespoon
• lemon juice
• yeast
• sugar

Instructions

1. Get your equipment.
2. Put your name on a disposable cup, preferrably plastic.
3. Put half a teaspoon of ginger into the cup.
4. Add half a cup of water into the cup.
5. Add one tablespoon of sugar into the cup.
6. Mix with a spoon.
7. Add 5 drops of lemon juice to the cup.
8. Taste it and adjust the flavour to perfection.
9. Add 1/4 of a teaspoon of yeast.
10. Let it brew for a week.

Results:

When I added the ginger to the lemon juice, it sort of looked like diarrhoea. When you mix it, it does not lose its brownish color but most of the ginger dissipated. When you add the yeast, the yeast will not dissipate easily. 

TASTE TEST:

It was absolutely horrible and I have nothing more to say about it.

Discussion:

The yeast (micro organism), a living thing, is going to try to "eat" the sugar and when it does, it will release a gas called carbon dioxide (CO2), and effectively, it is going to excrete (poop) out some Alcohol. CO2 is the same thing humans breathe. This process is called Fermentation. This is the same thing that happens while making bread. When the yeast excretes, it will form bubbles on the bread from the CO2. This full process is called Respiration.

The best conditions for brewing ginger beer is in a warm place and let it sit for approximately a week. The optimal temperature for proper ginger beer brewing is 21-29 degrees celsius.
