Sloomoo Institute is the perfect place for Birthdays and Celebrations for kids and kids-at-heart. Sloomoo’s world inspires escape, letting stress go, and joy.
Guests literally dig in with their hands (alcohol wipes are aplenty), add slime to the ever-growing Sloomoo & Repeat (slime wall), hurl slime with the Sloomoo Slingshot, explore Elmer’s Glue Kitchen, chill in an ASMR Sound Bath, customize their OWN slimes (over 4M combinations!), and indulge in journeys of scent.
Oh! And no visit is complete without walking across Lake Sloomoo (300 gallons of cloud
slime)... and potentially getting SLIMED at Sloomoo Falls.

A lifetime of memories
"There’s no place I’d rather be with 15 screaming kindergartners. Everyone was happy, busy, SAFE, and *healthy* afterwards. 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."
~ Mom to a six-year-old

Best birthday ever
"My 11-year-old and her friends had a blast - it was his best birthday ever. Our tour guide took such incredible care of us. When we saw the kitchen, we nearly lost our minds. The boys could not believe the amount of of materials there were and they did not want to leave."

The staff is super enthusiastic
"We had our daughter's birthday party here. It was a huge success. The Sloomoo team did everything to make sure the event was just perfect. They brought them a game and tended to the details. I could not have asked for a smoother team. The staff is super enthusiastic and wonderful."
