Customer Reviews

Growing Alligator Review by Michelle Horne

My 2 YO daughter inherited her parents love of science. She traced the small alligator, put it in the water, and asked about its growth every day for 3 days. We traced it again and talked about the science...she can now say 'hydrophobic' and 'hydrophilic'. It's pretty adorable. She also now carries the alligator all around and tells how he grew and shrank. This taught her new vocab, measuring, observing, patience, etc. LOVE IT!! (Posted on 5/11/13)

Test Tubes are the best tubes Review by Maggie Hunt

We bought several of these for our science fair to give out as prizes. They are perfect! We have six different prizes of Steve's most fun science toys and experiments. Each test tube has enough product to do the experiment at least three times. Super cute packaging! (Posted on 4/14/13)

Great way to introduce kids to science! Review by Angela Hackwell

I used these to hold down balloons at a 4-H awards banquet. These were used as door prizes. The kids loved them and were trading other kids tubes they wanted more. (Posted on 3/15/13)

Awesome for homeschooling! Review by Debi

I got these to use as experiments for our kids and they love them! Following the directions is easy and they have enjoyed the outcome each time. (Posted on 1/17/13)
