The Foam Party Machine should be placed on a grass from ymainpartch's blog

A Foam Party Machine is a great way to cool off your guests at your next pool party or outdoor birthday party. The machines work by spreading foam across a large area. Because the foam is all natural, it doesn't stain or irritate clothes. This is the best choice for parties with children. You can also use it as an add-on to a water slide to make the party even more fun. This rental machine is available for both indoor and outdoor use and is easy to set up and use.

The Foam Party Machine should be placed on a grass or hard surface. It may get slippery when it gets wet, so it's best to use a grassy surface. Be sure to run the extension cord away from the foam area, so it won't end up wet. The safety record of foam products is much better than that of inflatable bounce houses. This is why many people prefer them for parties. They can be set up in less than 5 minutes and are great for a variety of events.
