Just had fun

Jordan had THE BEST birthday!! Everyone had so much fun! The staff were incredible! Everyone was so kind & helpful. I would give this party a 12 out of 10!! Thank you for making my slime obsessed daughter feel so special!

Barbara B.

Refreshingly different

Truly unique. Hands-on, awesome, and refreshingly different.

Can’t wait to do it again

Everyone had a fabulous time and had so much fun! We LOVED it all! Everyone onsite was incredible and our activities were executed flawlessly. Can’t wait to do it again sometime.

Jessica P

Made the whole company jealous

Our division’s DIY slime made the whole company jealous - now four more divisions have booked.

Judi R

Everyone’s still talking about it

We came for a holiday party, and two years later everyone’s still talking about it. As busy execs, it’s rare to drop everything and feel like kids again. We needed it. We can’t wait to come back with our families.

Jason A

Had so much fun

My team was obsessed! At first, they all questioned the idea of Sloomoo Institute but they literally dove in, let their inhibitions go, and had so much fun. Now slime is a meeting prerequisite; they swear it helps them focus.

Catherine K

Nothing can beat slime

Our STEM campers’ favorite trip of the week, beating out other iconic NYC cultural institutions. Nothing can beat slime. Our students loved the interactive, hands-on play, and everyone took home slime.

Yesenia N, STEM Camp Director

Such a magical and memorable visit

Each room offered a unique, engaging, and sensory-filled adventure that truly captivated us all. Believe it or not, the fun wasn’t just for the girls - our parents had an amazing time, too! We’re already looking forward to returning - whether it’s with our Girl Scout troop again or with our families on our own. Thank you for such a magical and memorable visit.

Girl Scout Troop 24077

The UNANIMOUS favorite

Of everything our camp did this year, Sloomoo was the UNANIMOUS favorite day - by far.

Ruben G, Summer Camp Director

Loved it

We’re not sure who loved it more - the teachers or the kids! Now we fully understand the slime obsession.

Cindy F, 4th Grade Teacher

Science and magic

The kids were truly engaged and interested in understanding the science behind different textures of slime. Kids were blown away that they could make their own slime to take home. Science and magic

Ms O’Conner, School Principal

Spectacular experience

We hosted our daughter’s 8th at Sloomoo. The party team turned an already spectacular experience into a truly unforgettable birthday celebration. Huge thanks for a special day.

Dana W

Highly recommend

We just had what the kids called it “the best birthday party ever!” Booking with Nicko was effortless. Our party host, JooJoo, was full of energy and corralled the kids while leading them on an amazing experience! The highlight was slinging slime and the slime waterfall. Tired kids with full bellies meant happy parents. Highly recommend the experience.

Eliana P

A lifetime of memories

There’s no place I’d rather be with 15 happy kindergartners! Sloomoo took the best care of us, made the most epic custom slime cake, and the adults were well looked after too. A lifetime of memories. Thank you Sloomoo.

Julian A

Had a blast

My 11-year-old son and his friends had a blast - it was his best birthday ever. Our tour guide took amazing care of us. The slime kitchen blew their minds, and the boys didn’t want to leave.

Thea K

Left with huge smiles

My daughter’s 8th birthday at Sloomoo was an absolute hit! From the moment we walked in, the kids were mesmerized by the colorful, squishy fun from start to finish. The team made it seamless, and the kids left with huge smiles. My daughter and her friends left with huge smiles!
