Foam Party Rentals in St. Louis — FAQ
Do I need a permit for a foam party at a St. Louis City park?
Yes, permits are typically required for any special event or equipment setup in St. Louis City parks. It's best to check with the Parks Department for specific guidelines related to water-based activities.
What kind of power and water hookups are needed?
We generally need access to a standard 120V outlet and a garden hose spigot within 50 feet of the foam party area. Let us know if you have any unconventional hookup situations.
Can you set up in schoolyards or community fields?
Absolutely! We work with many St. Louis area schools and community organizations. Please ensure you have secured the necessary permissions from the school or facility administration prior to our arrival.
How much does a foam party cost?
Most foam party packages run $350–$800 for 1–2 hours of active foaming, including machine, foam solution, and attendant.
Is the foam safe for kids?
Yes — all reputable operators use hypoallergenic, biodegradable, tear-free foam solution that's safe for skin and clothes.
Does it stain or kill grass?
The foam is non-staining and biodegradable. Grass is fine — it usually rinses away with a hose.
