Measure 150m of 100° hot water in the measuring cup, pour in all the crystal powder and stir well.

After cooling to room temperature, open the lid of the dinosaur egg to make sure the dinosaur is standing in the egg.

Pour the solution into the dinosaur egg, so that the solution is more than 3cm below the back of the dinosaur.

Let stand for 4-7 days (the higher the temperature, the shorter the time required to stand), and observe the crystal growth.

After it grows to a certain size, slowly pour out the solution in the dinosaur egg and air dry for 2 hours.

Take out the dinosaur carefully and place it on the base.
