Heat sugar and water and keep stirring until sugar is completely dissolved
Use a juice extractor to extract the juice out of the cucumbers, you will need 1 cup of cucumber juice
Add the juice into a beaker or bowl
Use a citrus press or citrus juicer to get 1/2 cup of lime juice. DO NOT USE BOTTLED LIME JUICE...that crap's just too nasty!
Add the lime juice to the beaker.
Add 1 cup of the syrup made at step 1.
Strain the mixture onto a wide, shallow dish, I used an oven dish but feel free to use a plastic container.
Scrape with a fork, and continue freezing.
Repeat freezing and scrapping every hour till you are left with solid ice crystals.
