If you've ever wanted to make your own laboratory, look no further than this bag of science secrets.  This kit contains over 60 different experiments in a reusable bag.  Blast off with a soda explosion from a Geyser Tube‚ learn about the science of polymers including giant spheres, growing crystals, and Insta-Snow, learn about acids and bases, or even make your own slime... over 70 activities in all!  It's an ENORMOUS science kit containing loads of Spangler favorites for a great value.

The Big Bag of Science isn't just a bag of experiments, it's an experience. With the massive amount of projects and demonstrations, the Big Bag of Science makes a perfect gift for the young scientist in your life. Remember your first chemistry set?

Customer Reviews

Fun but needs improvements to work Review by Kim

Love all the experiments and excited to do them for my kids but disappointed that the descriptions on the bags and the descriptions in the instruction manual do not match. It asks for worm activator. I had to get online and watch the experiment to see that it was a calcium solution. I now know that the calcium chloride powder is worm activator. Then they also say just squirt in the worm soln but the bottle doesn't have a squirt top like the video shows. Lots of deductive reasoning needed to do these experiments. The labeling needs to coordinate with the instructions. (I am a middle school science teacher and had trouble figuring out what they wanted me to do).
In a different experiment I had to guess which crystals to use as there are a couple polymer crystals in the kit. I think any of them would work fine but better labeling would improve this kit.

Kim - 
Thank you for the feedback! We are aware of these problems and are working to get them changed as quickly as possible. Give us a call if you have any other problems and we'll do what we can to help!

School Teacher K-2 Review by Ginny Summerlin

Overall, this was a great product to expose kids to a wide variety of experiments. My class really enjoyed it. We had a little trouble with the labeling of ingredients. I will have to order another bag soon for my own children. (Posted on 3/2/13)

Not very happy Review by D.Shepard

We opened this kit to use and we are missing the instruction book....I am having a really hard time trying to find one as well. Not a very happy mom and 10 year old boy.

D. Shepard-

Big Bag of Science Review by Cindy Miller

Lots of fun things to do and learn from. Would of been a BIG help to know about all the items that needed to be perchased to complete the experiments before it was unwrapped as a gift. Items should be listed on the website in the description!!! (Posted on 12/3/12)

Share the Love and Science!!! Review by Terri Vrasich

I've enjoyed Steve Spangler products so much at the preschool I direct so I decided to buy this set for my granddaughter's preschool in Maryland. Here's hoping they will enjoy the many hands on experiences in this bag. (Posted on 11/21/12)

Confusion is in the bag Review by Adam Bonus

The science experiments are really cool...they are. But what's not really cool is the way a couple of the bags are labeled. For example, one experiment calls for "Non-Newtonian Powder." The only problem is that none of the bags of ingredients is labeled "Non-Newtonian Powder." What they actually mean is the bag labeled "Cornstarch." Unless you can read minds, it takes a lot of investigation to figure that out. Also, if the directions call for "Worm Activator" they actually mean "Calcium Chloride." This is all very frustrating when your 7 year old son (who LOVES science) wants to do a science experiment from the kit you just bought for him and has to wait while you search over and over for something that doesn't appear to be there.

Also, incidentally, we didn't receive the "Twister Tube" in our kit at all. (Posted on 10/2/12)

OK Review by Sarah

Overall, this was a decent product to expose kids to a wide variety of experiments, however, the products that were included were poorly labeled; we had to stop in the middle of a few things so I could get online to check to make sure we were using the correct ingredients. (Posted on 8/22/12)

Insta-Worm Hit! Review by Sharon

I am letting you know that the Insta-Worms were a great success for the 4-H project that we presented for our local Duck Days in Lake Crystal, MN. The 4-H Butternut Boosters relied on your services and delivered a fun, and exciting project for our club to present to the community. Thank you for your wonderful exploration into science, that makes science fun! You're Da' Bomb! (Posted on 8/9/12)
