Review: This is a great kit, So much fun ! - My son loves just about everything National Geographic puts out and he really wanted the Sensory Science kit this time, I was hesitant because I saw some not so great reviews, but decided to give it a go, and I’m so glad I did. All the items in the kit were excellent and great quality , I also have to mention that the play sand is the absolute best we have ever played with, The texture is soft and it molds well. We really love it. I saw some reviewers were not happy with the pink sand in the kit and also weren’t to happy with the magnetic putty. The pink sand and the magnetic putty we received was great , the sand was incredibly soft. The Magnetic putty was a little stiff , but it’s putty so kind of expected , however , after playing with it a bit it softens up. We have no complaints, my kid loves the kit and I even like playing with it too lol. I would also like to add that I was surprised that a really cool educational booklet came with the set and we learned some really cool facts about non-Newtonian fluid and also learned about how putty came into existence, it was very surprising. Overall this is a great value for the money there are so many cool things in this kit and will keep your child busy and you might enjoy playing with it too just like I did lol.
Review: Fun experiment - Super fun making and painting your own volcano child definitely has to have patience we use our own paints to make the colors brighter, but the eruption was quick but fun
