A picture of Neon Water.
Description
Neon Water is a liquid that seems to be water injected with some form of Neon. Like I said before, this is a rarity only being found on the last level of the Backrooms. Neon Water seems to be in many different varieties, where it may be in a bottle or a cup or even a bucket. Each time you find one of these varieties, the neon changes color. Each color is a different flavor (Orange for Orange, Blue for Blueberry, Yellow for Lemon, Red for Strawberry, Green for Apple, etc.). All flavors have been documented, but the file got lost deep in the Backrooms.
Properties
Neon Water seems to heal any disease it pleases. It also quenches your thirst quite well. On rare occasions, it gives you The Disease. However, this is easily avoidable as this happens every full blue moon. It can also help you levitate on the off chance that you have drank Almond Water a few minutes ago. Very few people have said they have drank Neon Water.
Locations
If you go in to the fabled Level 3999-3 and wear protective gear, you might survive the high amounts of radiation. Walk straight for 60 minutes, avoid the creatures, don't let the voices set in and you should come across a sign that says "Neon Water Dispensary". Walk in and enjoy the neon water.
There is Neon Water in Level 1009, however only very rarely, if you are a "good person."
There is also Neon Water in The Promised Land if you go in the infirmary. You can also find it in The Handy Machines in the Kitchen
