Who We Are

Host your child's birthday party in a science lab built just for kids! We host one party at a time, allowing us to give you and your guests our undivided attention. For the first 45 minutes, children put on little white lab coats and enter our lab to experiment with science gear (such as smoke ring blasters, rocket balloons and wailing UFO balls) and do awesome and messy hands-on science activities (such as making slime or erupting volcanoes). They then pass through the secret door (with a biometric lock that will only open with the birthday child's thumbprint!) into the party room, where they make drink concoctions using beakers and test tubes. At the end of the party, kids shout with delight as they leave their shadows behind on our glowing shadow wall!

C-Zone parties are 90 minutes long and include:

  • Hands-on activities & experiments in our kid-sized science lab. There are several age-appropriate themes to choose from for ages 2-10.
  • Play with our giant shadow wall.
  • Paper invitations and envelopes.
  • Balloons and table settings (cups, cake plates and utensils).
  • Drinks -- children make their own concoctions using beakers & test tubes.
  • C-Zone "goody beakers" (a mini science kit that includes a large beaker with test tube, pipette and experiment directions, plus other take-homes from the party; see party themes for specific details).
  • 20% off additional goody bag items from our toy store.

What Others Say

We've been to parties all over - from farm museums to homes to bounce-houses (Lots...and Lots... of bounce And don't get me wrong, I LOVE the bounce houses! We even had our daughters' fourth birthday party at a fantastic local bounce house. It's great exercise for kids and parents alike. But as a former science teacher I was really thrilled with what we experienced at this birthday party and I think it's so unique that I wanted to share my reflections on the day.

It was at an educational toy store/camp/class/party venue called Curiosity Zone in Ashburn, Virginia. Our friends signed up for their "Slime Time" Birthday Party for their five year olds. . . . It starts off with all the kids putting on adorable little science lab coats. The teacher worked them through three different science experiments. The first involved making their own bouncy ball using just water, colored glue and borax. The teacher was engaging and the kids were enthralled. They got to choose their own color for their bouncy ball (which was done in a really organized and fun way - having special hand signals for each color - my kids chose blue so both waited patiently with their hands on top of their heads until the blue glue came past their seat.)

Of course, it didn't take long with a room full of 4 and 5 year olds for the parents to get involved. Some of the kids were more than happy to stick their hands in all the gooey mess while others (mine included) wanted mom and dad's help with the gross stuff! Fun for kids and parents too! After the bouncy balls the room was split into two groups. One group made "flubber blubber," - a kind of slime. While the other played with something called "ew-blech." My apologies if that's not spelled correctly... but it sounds like exactly what you would say when you touch it "EWWWWW! BLECH!" A strange green substance that my husband said felt rubbery when you picked it up but them immediately melted into slime in your hands. Both groups then switched so that each child got to experience each station. And of course there was plenty of hand washing going on in between!

After all the slimy fun was over we headed to the party room for cake and ice cream - but probably one of the things I was most impressed with was that the learning didn't stop when the eating started. They had thought of creative ways to introduce scientific skills even during snack time. When the kids sat down, each seat was set with a straw, spoon, cup, beaker of water and a tray of test tubes. Using their scientific tools the kids were asked to pour their water from their beaker into their powder and mix it with their straw (making their lemonade). Then they were asked to choose a colored test tube to add to their drink and watch what happened as the colors mixed with the yellow lemonade.

It was such a simple idea... but honestly - this science-teacher mom hadn't thought of it before! I think it's so easy to take these everyday activities for granted - but kids are learning the basic skills of science, even when they help make lemonade. They were learning the vocabulary and basic tools of science (beakers and test tubes and all), having the fun of mixing it themselves, and learning about color mixing too. They could have just handed out juice boxes. But seriously... what would have been the fun in that! So simple - yet so great!

After the singing, and cake, ice cream and socializing, there was a cool "shadow wall" demonstration with glow in the dark paint and then each child left with a balloon, their bouncy ball and a sample baggie of flubber blubber (along with strict instructions NOT to put it on mom and dad's good furniture!), as well as their own beaker, test tube and pipette. But more than that, they left with an excitement for science. My five year old girls talked all the way home about the party and asked immediately if I would look on the computer for more experiments for them to do. We even purchased a beginner science kit a few days later at a local bookstore and probably this afternoon we'll start growing our first batch of rainbow crystals.

After we got home that night my husband told me that one of our daughters came running up to him during the party and said, "DADDY!! I FINALLY KNOW what I want to BE when I grow up! A SCIENTIST!!" It's so neat to see them so excited and engaged in learning. Of course, this was the same child that refused to touch the ooey-gooey rubber ball and made awful faces during ew-blech time... so we shall see...haha... but she did beg and beg on Monday morning to take her flubber blubber to school to show her teacher. What a great experience we had. And this is one party that I will remember for years to come! -- Blogger,

"You should definitely try the Curiosity Zone. My daughter went to a Slime Time birthday party there a few months ago and it was great, very professional, clean and FUN! The birthday boy was 6, but there were kids there as young as 3 and as old as 10 and the staff there did a great job of adapting the activities for everyone. The staff was SO friendly and they took care of everything. Everyone got a grab-bag filled with test tubes, balloons and a mini-science kit. My daughter still has her test tubes. We live in McLean and it was 15 minutes on the toll road. I commute an hour each way to work every day, so 15 minutes on the toll road on a Saturday was nothing." -- Anonymous,
