SmartLabToys Girls Only! Secret Message Lab with 25 Hidden Message Science Activities

I got this for my 8 year old granddaughter for Christmas and it is really fun! It has multiple ways to write secret messages and decode them along with a nice, colorful booklet of instructions and the science behind each method. It comes with 2 of everything including small carrying cases. They are not very sturdy though, but still a good value.

My 10 year old daughter.adores this kit. It comes with 2 complete kits (one for you and one for the person you want to send messages to) and a book describing how to create many different types of secret messages. She spent the entire day reading the book and creating several of the secret codes (mirror imaging, moon codes). The book also explains other secrets, for example if you hand your friend a note with your left hand, it means the opposite of whatever the note says. It also showed you different ways you can fold your secret note (into tulips and other origami type fold) What a blast this was for her and me (the person she choose as her best friend :) )

My daughters loved this gift, but it only lasted a few hours on a weekend before all of the materials were used up. So this toy isn't really a 'repeatable' toy that can be used again and again without being careful of rationing the play.

This is perfect for an 8 yr old girl. The kit includes invisible ink and different ways they can send codes in secret notes.

My box arrived damaged and the UV pens do not work. My daughter was so excited to use this. It’s a cute idea. We have additional UV pens that work and used it. However, I am extremely disappointed in the quality. Do you sell replacement pens?

My twin girls love this! It works via black light and they have tons of fun with it. Having a hard case for each of my daughters to keep their stuff in is awesome. Keeps it all together, and gives them a writing surface. All around great kit for a fantastic price.

I bought this for my granddaughter’s 10th birthday. I think it’s so important to expose girls to STEM activities at an early age. She not only had fun, but she learned a lot too!

My daughter loved this but the ink is messy! Will stain hands and rugs.
