Long Island's Mobile Slime Party — We Bring the Whole Experience To Your Curb
The only mobile slime party trailer on Long Island — serving all of Nassau & Suffolk County with zero travel fees. Birthdays, schools, camps, fairs and festivals. The birthday child is always free.
I love making slime, and wanted to give everyone the same experience"
- Emily M.
When Emily was 9 years old, she walked up to her parents and said she wanted to start a business. So they did what any logical parent would do — they had a custom mobile slime trailer built and launched Long Island's most colorful party on wheels.
Emily is 10 now, and she's been involved in every part of building Emily's Slime Party — Designing the trailer, testing slime recipes, choosing colors and charms, creating the custom labels, and working every single event alongside her family. She's not just the face of the brand. She runs it.
Every child who walks into our slime trailer or sits down at one of our in-home party tables gets the same experience Emily wanted to give them — a chance to make something totally their own. Custom colors, glitter, charms, and a personalized label to take home. No two slimes are ever the same.
Emily's Slime Party serves all of Nassau County and Suffolk County — from Garden City to Patchogue, Huntington to Long Beach — with zero travel fees, no hidden costs, and the birthday child always free. Family-run, fully mobile, and ready to pull up to your curb.

What sets us apart
Fully Mobile — We Bring the Slime to You
We load everything into our custom-wrapped mobile slime trailer and pull up right to your curb. No venue to rent, no setup for you to do, no cleanup when it's over. We bring the entire experience — workstations, supplies, music, party lights, and our team — directly to you anywhere in Nassau or Suffolk County.
A Family-Run Business With Heart
Emily's Slime Party is a family run business built on one idea — that kids deserve a party experience that lets them be creative, proud, and excited about what they made. Emily works every event. Her family runs every booking. You'll never deal with a call center or a franchise.
Personalization is the Core of What We Do
No two slimes are the same. Every child chooses their own colors, scents, glitter, and charms — and every container goes home with a custom label featuring the birthday child's name. Mixed-age groups, themed parties, schools, camps — we personalize for every group.
ANSWERS TO OUR
Frequently Asked Questions
What exactly is the Mobile Slime Experience?
Our Mobile Slime Experience is a fully equipped, custom-wrapped slime studio on wheels that we park right at your curb. It comes with built-in workstations, music, party lights, and everything needed to run a full slime party — no setup or cleanup required on your end. It truly transforms your street into a party venue from the moment we arrive.
How much space do I need for the mobile unit?
We need approximately 30 feet of clear space in your driveway or in front of your home — roughly the length of two car lengths. If you're not sure whether your space works, just send us a quick message and we'll help you figure it out.
Can parents come inside the mobile unit?
Absolutely! Unlike some mobile party services, we welcome parents inside. There's no waiting at the curb — everyone is part of the fun.
Is there a difference between the Mobile Experience and the In-Home Party?
Yes. The Mobile Slime Experience ($849) uses our custom trailer as the venue — it includes music, party lights, multiple slimes per child, and runs 90 minutes. The In-Home Party ($499) is set up at your home, backyard, or venue — it includes 1 slime per child and runs 60 minutes. Both packages include all supplies, custom labels, and our team on-site the whole time.
What happens if it rains on the day of our Mobile Experience?
Our mobile unit is fully enclosed so light rain is no problem at all — the party goes on! In the case of severe weather we'll work with you to reschedule at no penalty.
Does the mobile unit have electricity and lighting?
Yes — our unit is fully self-contained with lighting and power. Music, lights, and the full party atmosphere are all included with no need for you to provide anything.
Do you charge a travel fee?
Never. We serve all of Nassau and Suffolk County with no travel surcharges — not even to the Gold Coast towns on the North Shore. What you see is what you pay.
Is there a mandatory gratuity charge?
No. Some mobile party services add 20% gratuity automatically at checkout — we don't. Tips are always appreciated but never expected. Our team is here because they love what they do.
How many kids are included in a party?
It depends on the package. The Mobile Slime Experience includes up to 12 kids ($25 per additional child, 20 kids max). The In-Home Party Experience includes up to 12 kids ($20 per additional child). The birthday child is always free in both packages.
How long is each party?
The Mobile Slime Experience runs 90 minutes. The In-Home Party runs 60 minutes. Our team arrives 30 minutes early to handle all setup — so when the kids walk in, everything is ready and the full party time is theirs from the first minute.
Party time begins at the agreed start time regardless of guest arrival. If you'd like to delay the start, that time comes out of your party window. Need to run longer? No problem — additional time is available at $75 per 30 minutes, subject to availability.
What age range is best for a slime party?
All ages are welcome — including children under 5. Younger kids get extra one-on-one help from our team. Older kids get more creative freedom with advanced slime types, glitter, and charms. Mixed-age groups are totally fine.
Can the party be indoors or outdoors?
Yes to both. We can host slime parties indoors, outdoors, or under a tent — and our fully equipped mobile slime trailer pulls right up to your driveway for the ultimate outdoor party experience.
Do you bring tables and supplies?
Yes — we provide tables and seating for up to 12 kids, all mixing supplies, add-ins, decorations, aprons, and containers. Need seating for a larger group? We can accommodate additional tables and seating for an extra cost. Just let us know when booking.
Do you handle setup and cleanup?
Yes! We bring all equipment, set everything up, run the activity, and clean up when we’re finished.
Is the slime safe for kids?
Yes. All ingredients are kid-safe, washable, non-toxic, and commonly used in children’s craft slime kits.
Can kids choose their own slime type?
Yes — we offer color, scent, and texture customization. Higher-tier packages also include additional slime types like fluffy, butter, and cloud slime.
Can you theme the party for a specific child?
Yes — custom labels with the birthday child's name are included in every package. For a fully themed experience with personalized signage, that's available as an add-on. For schools, camps, and larger events, additional customization costs depend on group size — just ask us when booking.
Do parents need to help?
Nope — our team fully hosts and assists the children. Parents can relax or enjoy watching.
Do you offer upgrades or party add-ons?
Yes! We have fun premium upgrades like glow-in-the-dark slime, extra charms, glitter painting, balloon décor, custom labels, and even custom T-shirts. (Ask for pricing.)
What areas do you serve?
We serve all of Nassau County and Suffolk County — with zero travel surcharges anywhere. That includes Garden City, Massapequa, Levittown, Hicksville, Huntington, Smithtown, Babylon, Bay Shore, Patchogue, Bohemia, and every town in between. If you're on Long Island, we come to you.
Do you require a deposit?
Yes — a small deposit is required to secure your date. The remaining balance is due the day of the party.
How far in advance should I book?
We recommend 2–4 weeks in advance, especially for weekends, as those popular times fill first.
