About 5 years ago I made my own at home snowmaker. It was pretty easy to do if you have a good air compressor and some basic plumbing fittings. These parts and good cold dry air resulted in some pretty good snow my first time out. The cool part of doing this is the knowing the science behind making snow and being the coolest dad in your neighborhood!
It’s not just about shooting water into the air on a cold night(being a meteorologist helps). This is about compressing air and water then decompressing it inside the guns fittings.This process of creating super cooled water can allow you to make snow even when the temperature is hovering around 32°. IF you ever have sprayed compressed air out of a can you know how cold the can gets if you hold it down for while. This gun uses that same process of decompressing air and water to make it colder. Believe it or not the other most important part of snow making is the dry air. Low dew points allow for evaporative cooling which allows for making snow at or around 32°. While fun this can also be a great teaching tool about physics and science with your kids. Below is what is called a Tee gun and its the first and most simple method to making snow in your backyard.
Results my first time out and only after about 1-2 hours:
Here are all the fittings you need, they are all available at your local hardware store or Home Improvement store.
Here’s the assembly of the parts:
Now this gun does take a long to time to make snow depending on your compressor, water supply and the temperature and dew point. I’ve been able to make about a 6” deep pile of snow leaving it running overnight about 6-8 hours. Make sure though you have a heavy duty compressor with oil lubrication & cooling that is meant to run for hours at a time. If you want to make more snow at a quicker pace you’ll need to make a combo gun or fan gun. These type of snow makers are much more advance and take bigger compressors and a lot more money.

Enjoy, have fun and send me your pictures and videos to share on here and on TV.
