Review: Liked this way more than expected! - We received this item as part of the desertcart STEM kits subscription service (which we have really enjoyed). I would probably not have ordered this kit on my own otherwise as I think it looks kind of gimmicky and silly. When we got the kit I was obviously not super excited about this selection but all of the kits I have received before this have been well done, and my 12 year old was actually kind of excited by the packaging on this one. We finally got it out and set up and got a chance to play with it today. I was actually VERY IMPRESSED with this kit. We had a TON of fun using it and it was actually extremely well thought out, and did a really great job of it's task - helping kits understand gas and fluid dynamics. Here are some key points to help you decide if this kit is right for you: * - It does take some time, patience and effort to set it up. The tubes have to form air-tight seals in the containers, so that obviously means you have to push them in forcefully but without smashing them up. * - It is not the type of kit that you kid is going to get out, set up, play with and put away all by themselves without supervision and assistance. Setup and tear down aren't horrible, but it is enough that putting it back in the box is kid of a hassle if you plan to use it again soon. This is pretty typical for these kits and sets though, so I wouldn't consider it a deterrent to this particular kit. * - This kit adds fun things like baking soda a vinegar to make the whole thing more exciting along with lots of various experiments in the book that could really be done completely without the kit. For example, saturated salt water solution, comparing warm and cold water reacting with food coloring, testing ph, etc. A LOT of the stuff in the book has absolutely nothing to do with the kit itself. That may also seem like a deterrent to the kit. I mean, you don't actually NEED it to do the water and food coloring thing (you supply both the water and the food coloring), BUT it actually provides a really beautiful place to view the experiment and whole level of fun to later send the water through the various tubes and containers, etc. * - And that is where the kit really shines! The experiments themselves can certainly be done other ways with stuff I already had (I have a lot of science stuff), like we already have learned about air pressure by using little baby medicine syringes, but doing it with the fun plunger really helped it hit home for my son. Figuring out how to clean and empty the system without a horrible mess is actually the BEST part of this kit. He spent so much time watching the fluid levels in various things, seeing what happened when he opened valves, added water, added more air, etc. Nothing else we have done has been quite as engaging for him in terms of learning about fluid dynamics and air pressure as this kit has. * - The set is all around well made. You are certainly going to need to help an 8 year old. You are using a plunger on a pressurized system and it is attached in a top heavy way on an awkwardly shaped vertical surface....so, yes, it is a bit fiddly. But all of the pieces work properly and well, that system is air tight when properly assembled and the pieces have help up nicely with decently visible markings, etc. All around it seems very reasonably sturdy - I have not concerns about any of the pieces breaking under appropriate use cases. Review: Great product and service - Great value and was exactly what I wanted for my great nephew. ## Features - Explore the secrets of science with the unique experimentation station. - Endless fun.

One of the cylinder broke.** A: Did you try contacting the manufacture ? 1-866-319-5900 Most of the time they would replace it for you, give it a try! **Q: Can the experiments be done over and over or only once each?** A: This isn't just a typical science kit. This is your very own chemistry lab in a box!Made up of clear containers connected by winding tubes and valves - With just one look, this kit will have scientific imaginations reeling with excitement."It's just like a lab from the movies!"Open up the included lab manual and immediately kids start learning by doing.Start with the basics of air pressure and fluid dynamics as you try pushing the plunger with the valves opened, closed, with different containers filled, emptied, and with the tubes pushed above and below the water lines.Explore chemical reactions with different substances from around the house (e.g. baking soda and vinegar) and then use your lab contraption to see the effects those reactions have on the surrounding atmosphere.It even comes with pH strips you can use to test whether something's an acid or base - Then you can experiment with them! - (Though, of course, some chemicals will definitely require adult supervision. Safety first!)Finally, once you finish working though all forty of the experiments in the book, the fun STILL isn't over - Kids are encouraged to use all they've learned to set up and conduct all kinds of their OWN experiments.It's just like a real science lab - The exploration excitement never stops!Complete with all the tools you need, easy-to-follow instructions, and real scientific explanations for EVERYTHING, the Ultimate Secret Formula Lab is definitely a must-have for any and all kid scientists.SmartLab Ultimate Secret Formula LabReal chemistry lab for experimenting with air pressure, fluid dynamics, chemical reactions, and moreEncourages scientific learning, logic, critical thinking, creativity, curiosityKids become real scientists!40 experiments guide kids through real scientific principles including air pressure, fluid dynamics, acids, bases, and moreExperiments feature easy step-by-step instructions for set up, experiment, and safetyEach experiment features detailed scientific explanations kids can easily understandIllustrated lab manual and instructions includedSpill tray measures 17.75 x 11.25 x 0.75 inchesHigh quality design and materials for exceptional learning experienceIncluded: 3 structure support pieces, spill containment tray, contraption base, 3 valves, 2 elevated reservoirs, pneumatic plunger, plunger container, lid for elevated reservoirs, modular superstructure, 2 mixing vessels with lids featuring holes for tubes, ending container, 2 small tubes, medium tube, 2 long tubes, Petri dish with lid, Erlenmeyer flask, beaker, pipette, non-skid pads, pH strips, calcium chloride, calcium hydroxide, phenol red solutionIngredients Used in Some of the Experiments, Required From Home: Active dry yeast, alum powder (find with spices), Ammonia (ADULT ASSISTANCE REQUIRED), baking soda, carbonated water, diet and regular soda, dish soap, epsom salt, food colors, fresh marshmallows, hydrogen peroxide solution (3%), lemon juice, milk, raw potato, red or purple cabbage, salt, sugar, white vinegar (distilled) **Q: Is it fun for a 12 yr old?** A: If your 12 year old is really into science experiments, I think so. I am using it with my 6 and 7 year old. We have done half the experiments and they love them!!!! Would do them all, one after the other if I had the energy. :-) **Q: I know it’s recommended for ages 8+, but would a 7yo understand and enjoy this?** A: Yes definitely- but plenty of parental involvement is needed to understand the experiments. And be gentle with the equipment, it breaks easily. But the company is great about replacing parts free of charge. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Liked this way more than expected! *by R***R on October 17, 2018* We received this item as part of the Amazon STEM kits subscription service (which we have really enjoyed).

Bought it for my 4yr old for Christmas. 1 star down due to it being rather difficult to put together (it say's 8 and up, but I'm not sure an 8 yr old could get some of the tubes in the beakers) and for the fact that once it's together there is no taking it apart. Otherwise, it's been fun. Definitely something to do WITH your kids as there are actual chemicals included. You do need some things from home for a few experiments (which I expected), but nothing crazy or expensive. We have had a lot of fun with it so far. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/24798649-toys-ultimate-secret-formula-lab-with-40-experiments](https://www.desertcart.tn/products/24798649-toys-ultimate-secret-formula-lab-with-40-experiments) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-07*
