Staffed foam party: the Signature Foam Experience

A trained River City attendant runs a commercial foam cannon at your home, with white foam and party music during your foam time, plus setup, operation and breakdown. It's staffed only, with no drop-off or self-run option. Choose 1 hour or 2 hours of foam session time for a private residence. Want the pit too? The Foam Yard + Foam Pit Combo adds the Inflatable Foam Pit + Archery Game, a 24-hour equipment rental, to a 2-hour staffed foam session.

What's included

Running it yourself? The DIY Residential Foam Cannon Party Kit is River City's residential foam machine plus soap for about 1 hour of foam. You set it up and run it; it isn't a staffed commercial cannon. Pick it up, or get delivery with a quick-start walkthrough. Foam session time: about 1 hour of foam. Rental window: Rentals include a full 24 hours of use, with pickup at the end of the 24-hour window. Need more foam? Add 1 Hour of Foam Mix (DIY). Colors, UV glow and gender reveal foam are for the staffed party only, not the DIY kit.

The Inflatable Foam Pit + Archery Game is a walled 20' x 20' inflatable (listing size) that holds the foam in one play area and also works as an archery game arena. River City setup space is about 26' x 26'. When it's used with foam, it goes on grass (no concrete, pavers or indoors).

• Foam Yard + Foam Pit Combo: a 2-hour staffed foam party plus the pit for 24 hours. Up to 25 participants at a time in the pit (manufacturer limit per current listing), ages 3+.
• Backyard Foam Bash: the foam pit plus the DIY kit. You run the foam and no River City staff stay on site.
• Foam Pit + Giant Twister Package: the pit with a giant Twister banner and dice for dry play. The banner comes off before foam.

Rental window for the foam pit and its packages: Rentals include a full 24 hours of use, with pickup at the end of the 24-hour window. Staffed foam session time (1 or 2 hours) is separate from that window.

UV Glow Foam Color turns a staffed foam party into a glow party after dark. The foam glows under UV black lights that your attendant brings and sets up around the foam zone. White or neon clothes glow best. Glow parties start at least 30 minutes after sunset and end by 11 PM. It's a Signature Foam Experience add-on only.

Swap white foam for orange, green, purple, pink or blue, then add a Second Foam Color for two colors at one event. For a gender reveal, guests play in white foam, then at your countdown the attendant switches the cannon to pink or blue. Hand the attendant the sealed envelope (or have your doctor's office send it to us) and we keep it secret. Colors are add-ons to the staffed party only, and colored foam may lightly tint clothing.

Foam for a school field day, end-of-year party, church event, VBS week, or an HOA or community day is quote only. Tell us your date, venue, crowd size and water access, and we'll quote it. Call or text (210) 471-8797. Pair it with inflatable games and concessions from our school and church events page.

• Bubble Machine Add-On: a Bubble King professional bubble machine run by your attendant during a staffed foam party. Bubble solution included; needs 1 standard outlet.
• Bubble Machine Drop-Off Rental: a Bubble King machine dropped off for you to run, with bubble solution for about 5 hours. Needs 1 standard outlet.

Foam needs water. No spigot or hose bib? Add No Water On Site: 200-Gallon Water Delivery. We truck in enough for about 1 hour of foam (foam parties only). Delivery is $20 within 10 miles of our west San Antonio base, then $5 per mile up to 25 miles; over 25 by quote: call or text (210) 471-8797. Online orders have a $169 online minimum.
