Good purchase for young boy
on December 27, 2017
Bought this for my 6.5-year-old nephew. He was so excited to open this and see all the eggs! He had fun guessing which type of dinosaur was inside the egg. We put one in water overnight and it "hatched" in about 12 hours. Basically, the egg has holes int he top so when you submerge it, you can get out all the air inside the egg and fill it with water. The dinosaur inside is made from foam and will expand in water. As the dinosaur expands, it pushes on the outside of the egg, which also starts to dissolve and crack from sitting in the water. I'm not sure what the eggshell is made from, but it was really quite hard. Nephew read the box and insisted that it would take 24-48 hours to hatch, but it took less. Even after only 4 hours, the cracking was noticeable. A good idea to put it in the water before bed so the child can wake up to a hatched egg. The foam dinosaurs aren't anything special, but they were slightly more detailed and smaller than I was expecting.
The set also came with stamps. There was some mild outgassing when I opened the box. Each egg is packaged in a plastic housing which the child can easily open.
