Customer Reviews

Great Kit -- shipping is pricey Review by Tony J

I ordered the kit for a Harry Potter Themed Birthday Party for my twin 9-year old boys. The experiments were definitely a big hit -- and allowed each kid to bring home some Dragon Snot Potion(Atomic Slime), some Mermaid Eggs (Clear Spheres), Pensieve Memories (Insta-worms) and Boggart Decoys (Screaming Balloons). We had some great demonstrations with dry ice and the gravi-goo. Overall a hit. I only dropped a star because the shipping cost was far too high ($176 standard). I know I live in Hawaii but I still get free shipping from Amazon Prime and many other retailers use USPS to cut down on shipping tremendously. I would love to try more products from Steve Spangler for our kid's classes or cub scout troop but unless they find a more reasonable shipping method I cannot justify it. (Posted on 5/29/14)

GREAT Review by Erin Dennis

This kit kept Kindergarten busy for four hours and it was SO interesting. I'd recommend this to anyone! The only experiment that I'd skip is the gravigoo. When it fell on the ground (tiles) it was so slippery that we were all falling on top of each other. Nothing cleaned it up. I had to use sawdust to soak up the mess and then clean. It took several hours to clean up after gravigoo. But everything else was fun, easy clean up and fascinating. Parents that helped me in the classroom were amazed and many went out and purchased dry ice for their own experiments. You know it's good when a five year old asks for the website to do more!

Not Just for Halloween Review by Cyndy

We purchased this lesson as a bonus lesson for winning classrooms of a contest. I did the lesson with both a Kinder class and a 3rd grade class on St. Patrick's day and what a huge success!!! Both grade levels learned a great deal and had a blast at the same time!
Thanks so much (Posted on 3/30/13)

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 2/7/13)
