NATIONAL GEOGRAPHIC Craft Kits for Kids - Crystal Growing Kit - Grow a Crystal Garden in Just 6 Hours, Educational Craft Art Project, STEM Crafts for Girls Ages 8 9 10 11 & 12 (Amazon Exclusive)

This National Geographic Crystal Growing Kit is easy to do and comes complete with everything you need to create two crystal trees. You get two trays stands 2 trees, 5 colored washable markers, and 1 bottle of crystal growing liquid. The instructions are straightforward so that an 8 year old and up with supervision can easily create these crystal trees in about 30 minutes and after 6-8 hours the crystal trees will be complete. I love how this comes with a learning guide so you and your child (children) can learn how crystals are formed. I also like how National Geographic even included a Geode specimen inside. Overall a great Stem Kit that's not only educational but fun too!

My 8 year old really liked this project. Color the trees, pour in the solution. There were already small crystals within an hour, and we woke up to full crystal trees! The crystals feel like foam, and they do crumble when you touch them. Definitely not something that will last, but lots of fun to do.

The only thing I’ll say was a negative is that the crystals don’t harden which I wasn’t aware of when I bought this. They grow quickly (takes a few hours) and my daughters loved them.

We had a great time watching the crystals form. Once they started showing growth it was fun to check the development every 30 minutes or so.

The instructions were clear. The trees were easy and fun to color. The markers were not great quality. We bought 3 kits and each one had a dried out marker. The kids really enjoyed waiting for the crystals to form and watch them grow. However, the “crystals” were more like “snowflakes.” I was expecting the “crystals” to be hard but they were fluffy. My4-year-olds enjoyed the activity more than my 6-year-old. I wish included in the instructions there was more emphasis on the science of the growing crystals. I was hoping to have made it more into a science Lesson/learning activity without having to research on our own how the “liquid” turns to “crystal”

The media could not be loaded. This was very fun to do with my daughter. I was very impressed to see it grow the way it did. If your tree doesn’t grow it’s because of something you did wrong . It started to grow in about 30 minutes or so now the crystals are very delicate and will fall off I enjoyed it all so thank you

They came out amazing!! The only thing is if you want them to last that won't happen. It falls off of them, very easy and feels like shaving cream. very neat though and easy enough to do with a two-year-old. (The coloring part that is)
