Open Lab is the simplest thing we do — the thing families come back for most. You reserve a slot, show up, and your family works through real, hands-on science experiments together, at your own pace. No enrollment. No semester. No stage with a presenter. It’s one of the easiest things to do with kids on a rainy-day afternoon, or any afternoon. It’s also the question I answer most often: so what exactly is Open Lab? Here’s the complete answer: how it works, what it costs your Saturday, what kids do at the stations, and when it’s the right choice versus a party, camp, or class.
Key Takeaways
- Open Lab is reserved, self-guided science: 30+ experiments across 6 stations that your family runs yourselves, with lab coats and safety glasses included.
- An hour is the natural visit; most families get through about 3–5 experiments, and you reserve your slot online before you come.
- Parents participate, and that’s a feature: family science time measurably counts as real learning.
- It’s the founding offering of Little Beakers — built so any family could afford one inspiring hour, no commitment required.
- Pay-per-visit first; membership when your family starts asking to go back.
What Open Lab Covers
Open Lab is a standing session at each Little Beakers location where the lab is open to families. You choose from 30+ experiments across 6 stations — chemistry, physics, biology — each set up with instructions and materials, and you run them yourselves. Lab coats and safety glasses are included; an adult stays and works alongside the kids. It’s one of our most popular indoor activities for kids, and the front door to everything else we do. This guide covers the mechanics, the science case, the local details, and how it stacks up against our other formats.
How Open Lab Works, Step by Step
- Reserve a slot on our website. Hours vary week to week and the lab may be hosting a 100+ student field trip, so booking (or at least calling ahead) is the way in. We’re flexible on exact start times.
- Gear up. Lab coats and safety glasses are provided, sized down to the smallest scientists.
- Choose your experiments. Each of the 30+ experiments comes with instructions and materials ready to go. Follow the procedure, gather your materials, run your experiment.
- Go at your kid’s pace. Most families run about 3–5 experiments in an hour — but blazing through ten experiments and spending the whole visit perfecting one are both doing it right.
- Come back. Experiments rotate, so returning families keep finding new science. Families who get hooked switch from pay-per-visit to a membership and make it a routine.
And to prevent the two most common mix-ups: Open Lab is not a drop-off (that’s Parents’ Night Out — an adult stays and participates here). And it’s not a class either (nobody’s leading a lesson; your family sets the pace and the playlist). It’s the self-serve aisle of the lab, deliberately.
Why We Built It This Way
Our founder started Little Beakers on one conviction: any family should be able to walk in — even for just one hour. Their child should be able to use real equipment there and get inspired. No big commitment standing between a curious kid and a lab bench. That’s Open Lab. It exists specifically to remove the barrier.
It’s also why everybody comes in. An hour of science is an outing any family can say yes to — the same way you’d say yes to the park or the library. Except here, the library fizzes.
And the science backs the design. The National Academies’ report Learning Science in Informal Environments found that real science learning happens in exactly these settings: science centers, family activity, everyday experience. It’s not only in classrooms. Meanwhile, hands-on activity measurably builds science motivation even in preschoolers. One self-guided family hour sits right where both findings meet.
What Kids Actually Do at the Stations
Real experiments, kid-run: mixing reactions with real labware, building circuits, testing magnets, making polymers, bending light. The mix spans chemistry, physics, and biology, and the stations scale — the same bench runs simpler for a 4-year-old and deeper for a 14-year-old. Ages 2 to 16, every kid finds their station. (Fair warning from experience: half the parents get more into it than the children.) That’s allowed — encouraged, honestly. Participation is the point, and per the evidence on active learning, it’s also how the learning actually happens.
A Tour of the Station Types
“30+ experiments” is a number; here’s what it feels like from the bench. Stations cluster into families, and most visits sample several:
Reactions. The crowd-pleasers — acid-base chemistry, color changes, fizzes and foams, run in real labware with real measuring. This is where most first-timers start, because the payoff is immediate and repeatable.
Build-and-test experiments. Physics you assemble: circuits, magnets, structures. These reward the kid who wants to modify the design and run it again — which is to say, they teach engineering practice without ever using the phrase.
Materials and polymers. Slime’s serious cousins — kids make substances and then investigate the properties of the thing they made. Making something and then studying your own creation is a big one-two for a seven-year-old. And they get to take their creations home!
Optics and perception experiments. Light-bending, lenses, illusions — the quiet experiments, great for the kid who needs a lower-stimulation corner of the lab, and for the “one more experiment” wind-down before you leave.
Biology experiments. Observation-first life science, with microscopes and magnification — no specimens or dissections in Open Lab. Families who get hooked here step up to guided dissection classes.
Rotation means the exact lineup shifts between visits — the practical tip is to let your child pick the first experiment, then steer the second toward a family they skipped. Over a few visits you’ll watch a map of your child’s mind draw itself. The kid who always starts at reactions but lingers longest at circuits is telling you something no aptitude quiz can.
First-Visit Tips From the Front Desk
- Plan on an hour of lab time — and don’t feel rushed. A session is one hour of actual lab time; we allow a few minutes of warm-up and never hurry a family off its last experiment, so most visits run a little over. The magic tends to start at experiment two.
- Dress for science. Closed-toe shoes, clothes that can take a splash. We provide the lab coats and safety glasses, but sleeves are your department.
- Let the kid drive. The strongest visits are the ones where the adult resists curating. Your child’s experiment choices are data — that’s the “which program fits” question answering itself in real time.
- Bring every kid. The 2–16 range is real; siblings can work parallel stations and experiments at their own levels, which beats one bored sibling orbiting the engaged one.
- Ask the staff for the “one more” pick. Our team knows which experiment converts skeptics. Use them.
Open Lab vs. Party vs. Camp vs. Class: When Each Fits
Open Lab is the right choice for:
- A first visit — the no-commitment answer to will my kid even like this?
- Rainy days, school breaks, and I’m bored afternoons.
- Homeschool families adding hands-on time to their week.
- A regular family outing that doesn’t cost a fortune.
Choose something else when:
- It’s a birthday — a science birthday party gets you a scientist-led session and a private party room.
- Your kid wants a week-long deep dive on one theme — that’s camp territory.
- You want weekly structured instruction — that’s classes.
- You want an evening off — that’s Parents’ Night Out, the drop-off version.
The Membership Math (When Pay-Per-Visit Stops Making Sense)
Here’s the honest framework, without quoting prices that change:
Visit one and two: always pay-per-visit. You’re still answering “does my family love this?” Never buy a membership on a first visit, ours or anyone’s — enthusiasm at the register is not data. Two visits is data.
The signal to watch for: unprompted requests. When can we go back to the lab? starts coming from the back seat unprompted, your family has a habit forming — and habits are what memberships price for.
The comparison to run: count your realistic monthly visits, multiply by the per-visit cost, and set it against the membership rate at your location. Most families who visit even a couple of times a month find the membership flips the math. The mindset flips with it too: a membership converts should we spend money on the lab today? into the lab is already ours, let’s go. That second framing is what turns science into a family routine instead of an occasional treat.
What memberships are really for: removing the decision. The families who get the most from the lab aren’t the ones who had one big visit — they’re the ones for whom Tuesday-after-school-lab just became a thing that happens. Current options and rates live with your local lab — ask at the desk or check the memberships page.
Open Lab for Grandparents, Caregivers, and the Non-Science Parent
Two groups deserve a direct word.
Grandparents and caregivers: Open Lab may be the best grandparent outing ever made — seated-friendly, weather-proof, one hour. And it produces the thing grandparents actually want: a shared story — we made a polymer, and YOUR mother would never let us do that at home. The adult-participation rule isn’t a burden here; it’s the point. No science background required — every station carries its own instructions, and staff are a hand-raise away.
The parent who “isn’t a science person”: you’re the most important adult in this whole guide. When a kid watches a parent read unfamiliar instructions, try something, get it wrong, and try again — that models more real science than a perfect demonstration ever could. You don’t need to know the answers. You need to sit at the bench and be willing to find out. The lab handles the rest.
Open Lab Around Houston and Salt Lake City
Open Lab runs at all five locations: Cypress, The Woodlands, and Katy/Memorial around Houston; Sandy and Orem in Utah. Hours vary by location and by school-year season, so check your local lab’s schedule, and reserve your slot online before you come.
What One Hour Can Start
Here’s the outcome that makes Open Lab worth explaining at this length: it’s the cheapest possible way to find out who your kid is at a lab bench. One hour tells you whether you have a chemistry kid, a circuits kid, a materials-and-polymers kid — or a kid who just had a great Saturday, which also counts. Families tell us the ride home is the tell: when the “what happens if we…?” questions start before you’ve left the parking lot, you’ll know. (Why that question matters so much is the subject of our founder’s complete guide to hands-on science for kids.)
What to Do Next
- Check your nearest location’s Open Lab schedule and reserve a slot.
- Budget one hour and expect to run 3–5 experiments as a family.
- Watch which experiment your child won’t leave — that’s your signal for what to book next.
- If the ride home is full of “can we go back?” — look at memberships; that’s exactly who they’re for.

Open Lab FAQs
Do I need a reservation for Open Lab?
Reserve a slot on our website. Hours vary week to week and the lab may be hosting a 100+ student field trip, so booking (or at least calling ahead) is the way in. We’re flexible on exact start times.
How long does an Open Lab visit last?
Most families find an hour is right, and typically run about 3–5 experiments in that time. Stay longer if the lab’s schedule allows and your kids are still going.
Do parents participate in Open Lab?
Yes — an adult stays with the kids and works through the experiments alongside them. Most parents end up elbow-deep.
What’s included with an Open Lab visit?
Lab coats, safety glasses, and access to all available experiments — instructions and materials included with each one.
Is pay-per-visit or a membership better?
Try pay-per-visit first. When your family starts asking to go back, a membership starts paying for itself — your local lab can walk you through current options.
