I'm selling snowguns for people who want to make snow at their houses. It is very inexpensive to run (less than a washer) and they are alot of fun to use. They start at $45, $65 and $85. Requirements for all of them are an air compressor and water hose. The larger one ($85) requires a pressure washer. Air compressors go for less than $50 on Ebay or you can get them at your hardware store for around $75. You can either get an electric pressure washer or a gas one. The gas ones are more expensive but are more powerful. Electric pressure washers are about $75. They put out between 1-5 in per hour and work at below freezing temps. Message me if you want one.
Hopefully this will work better than my last try
