Does garlic kill germs?

Garlic Juice

I had a few request to test whether or not garlic could kill germs. So, I got a clove of garlic and ground it up in my garlic twist. 

I added a little water and mixed it up to make "garlic juice". 

I tested .5mL of this garlic juice on a dirty countertop square for 5 minutes just like I do the cleaning product experiments. There does seem to be a small decrease in the amount of bacteria. I really need to repeat this one a few more times to be sure. The plate labeled "garlic juice by itself" was just a swab of the garlic juice to make sure that it did not contain bacteria.
