    Slimes
    Steph M.

    Slime factory in Factoria Mall- park by nordstrom rack or Panera was a great rainy day kids activity in Bellevue. We made reservations online same day. Booking online automatically gave a 10% discount. Its located across from Jamba Juice/ Sushi. We arrived early but that was pointless as we had to wait until after 4:10 to get started. The employee was on cell phone when we arrived to check in. Not very welcoming. But I get maybe it's the only time In between sessions they have to break? Before we got started the giant slime in tub in back of as a hit. 2 out of 3 paper towel holders were clogged though. During the demonstration I felt like the instructions were hard to hear. They weren't really "little kid silly". More just monotone. So the overall experience was to make slime. Not so much entertainment performance. They were helpful but I was annoyed we had to wait 10 minutes to get started after the reservation time because a group was running late. I felt like they should start on time and for those who come late- maybe they have an instruction sheet at the station to catch up? Playing with the giant tub of slime was a hit. Our 4pm group had about 10 active kids. Ages ranged from 3- 10 ish. Instructions for the littles were fine but they need help. I was fine to sit on side without helping for 8-10 year olds. Cons: --Getting started late. We shouldn't have to wait for those people who are late. --no Sink! They ended up being covered in shaving cream and glitter when exiting. Was a big pain. -- all the seating was hard and uncomfortable and coveted with glitter --no bathroom in the slime factory. Have to go out around by nordstrom rack which is not within eye sight. --only allowed 1 charm per slime and it was only a flip flop or retro girls looking sunglasses. When my son asked for 2 flip flops they were really strict even though a girl with us didn't want any. --only 2 scents - cotton candy or lavender. Would be nice to have more options. --no bags to put slime in. Made shopping afterwards a pain. Note- I placed a red robin to go order when they started so we could pick up and have food right afterwards. It took 45 minutes to do. The kids loved it. It was definitely a one time activity. Can't picture coming back to do it but would be a fun birthday party activity.

    My son wanted to go for his 9th bday. Make sure you make your reservation online. We went one day because we thought you could do walk ins. Maybe yuh can I'm not sure but I we went during regular hours and it was closed so we made a reservation and went back a different day. My boys enjoyed it a lot. Definitely a great place to celebrate a birthday or just to do something fun as a group. It was a very organized fun bday celebration. We will would go back again. Thank you for making our sons birthday special he had a blast!

    A rushed assembly line. Not fun.

    What a flop - not a recommend from me. We went today and the whole experience was so rushed and unpleasant. It was from start to finish 30 minutes. It felt like an assembly line where the employees asked kids to make decisions within seconds "which color sprinkles do you want" and the employees would do it themselves and hand back to the kids. Not at all engaging or immersive. There was no playing or enjoying it, it was chaotic and rushed. A few other negatives - they coordinate each experience in time blocks so you're in a group with whoever else booked that same time which in our case included a birthday party. We started 15 minutes late because the birthday party guests hadn't all arrived. It was also strange to have the birthday party space in the same room so our kids were smelling pizza the whole time that they weren't going to enjoy. Not a huge deal but it wasn't great. Another big miss is that they have no hand washing station! This is nuts to me. The kids (and grown ups) have sticky gooey globs all over and you have to walk half way across the mall to the public bathroom to wash your hands. I understand not having a full bathroom but I would expect something more than hand sanitizer and paper towels in a Slime experience. And for my 2 kids it was $68!!!! For 30 minutes of "entertainment" and 2 slimes, no thanks. My kids have waaaay more fun at other activities that are more engaging and last longer. Won't be back

    There is a shop where you can play with slime at Bellevue Factory Mall   Children are always happily playing with slime, and I feel that it is excellent in terms of safety and cleanliness.   Playing with slime is a great way to develop your child's creativity. You can stretch it out, roll it up in the palm of your hand, and play with it freely as you think of it. I think it's the only place in Seattle

    What a fun activity! Definitely make reservations online to make sure you can get it in. We went on a Monday afternoon because unfortunately most kid things are closed on Mondays like children's museums etc. But bonus it's actually way cheaper on a weekday so it was perfect! My 4 year old son did the express because thats all his attention span could handle while my 8 year old did the full experience and absolutely loved it. Luckily it's in the Factoria Mall just across from Lakesshore Learning Store so we went there afterwards and looked at the toys. Bring some quarters if you can as inside the mall they have those coin operated machines and candy. The slime wall where you throw the slime that you don't want to take home is my favorite. It reminds me of the Gum Wall at Pike Place Market but just more hygienic. We took about an hour there because they had this epic green slime table that you can just play in after your experience. Highly recommend going especially when it's cold and wet outside!

    Great birthday experience for my 5 year old! The recommended age is 5 and up, but my 2.5 year old was able to join in on the fun as long as she had full parental supervision. Highly recommend this place!

    They bring slime to next level. They have various colors, glitters, foam and SCENTS. My son and I had lots of fun making our unique slime. It was a great family activity. The owner was also very patient. She made sure our slimes were in perfect texture to do all sort of fun things (e.g. using slime to make sound like popping bubble wrap, making giant bubble, etc.). Will definitely return.

    I've been to the slime factory several times and the atmosphere is very friendly and fun. The staff always plays with the kids and makes the whole experience amazing. And they even keep the slime in cute little containers! The little ones absolutely adore the instant snow pool. My daughter always wants new slime constantly so this experience makes her appreciate the slime she got to make and take home with a marshmallow smell. she's a real slime scientist. 10/10 will be back again soon.

    It's a fun place for kids who love to play with slime. My son was happy to make bubbles with slime and then also play in the slime pool.

    My son had fun but the owner brought her kids. Her daughter was extremely disrespectful and told my husband to shut up.

They have a small arcade area when you walk in. You can also pay to play with the steam tables in a different section. There are snacks and some bites of food sold inside. I didn't notice much people opting for it. I would def recommend bringing a water bottle in, they are $2.50 a bottle inside. There was free black coffee set out for parents, but I didn't see any creamer. Two restrooms inside that were big, nice and clean. The kids had fun jumping in the ball pit, foam pit, some trampoline. There is a fun beaded pit with some toys to play with. Great place to burn the kids energy for the day.

Everyone at the birthday party had a blast and kids played so much they were tired!!! A super fun and successful birthday. Highly recommend for a kids birthday!!

The employees walk around constantly, showing they care about the place and taking good care of it. The only annoying thing is their claim that you must buy their specific brand of socks because of "insurance policies." That is total crap. No insurance company mandates a specific retail brand name of socks; they only care about general safety and grip. Using that excuse feels a little insulting to me. However, I don't care too much i'll buy the socks without doubt and support the business, because this is a great place. We will definitely come back here all the time because the facility itself is amazing! Thanks all we are more than happy to continue giving you our business

Online ticket reservation was easy, paying for just the child's ticket while adults are free (phew). Reading previous reviews, it seems they gave out their own grippy socks at one point, but I came prepared with my son having his own which was fine per the front desk. The interior is well thought out and planned for kids to go around exploring: 2 indoor climbing structures, 2 excavator pits (literally the most unique attraction that we never had ourselves growing up), a small child/ young toddler area, and pretend play police/fire station, movie theater and 3 ride-on animals. There's ample comfy seating for adults to lounge, because we all need to dissociate from our kids at times. Overall the environment was clean, nothing looked too worn down outside expectations, and all the staff were friendly. If you plan on spending 2+ hours here, the young ones will get hungry, which leaves you at the mercy of having to pay on-site inflation for snacks or a bulkier meal; at least the options are relatively "healthier" for kids, but you should lower expectations for yourself. Personally I could've made that $8 cup of mac and cheese better... all while avoiding a curdled cheese sauce. I'd like to think $25 admission for a weekday AM was sufficient to give my 4yo the space he needed, but crowds can still build up by mid-AM; I don't foresee smaller toddlers doing well if you are worried about the bigger kids possibly trampling over them. Heads up, just received an email that they're increasing prices and mandating their own $5 grippy socks, as I'm typing this near the end of March 2026 :(

During hanging and obstacle exercises, there were moments when children needed help but no coach was nearby to assist or spot them safely. For a ninja-style program involving climbing, swinging, and elevated obstacles, consistent supervision and equal attention to all children should be a basic expectation. What was also disappointing was the lack of concern or follow-up when we chose to withdraw. No one asked why we were leaving or seemed interested in understanding our experience, which left us with the impression that parent feedback and individual student experiences were not being taken very seriously. For parents considering this program, I would recommend paying close attention not only to the facility itself, but also to how consistently all children are supervised, guided, and included during class.
