Boric acid: 8%~ 10%
Corn starch: 90%~92%

The specific approach is as follows:
1. First, mix boric acid and food coloring evenly.
2. Add the corn starch into the boric acid solution, and fully stir it evenly.
3. Add proper amount of water and make dough.
4. Divide the dough into several parts and add different pigments according to your own needs.
5. Stuff the dough with uniform color into the eggshell and tighten the eggshell.
6. Put the eggshell with dough in warm water, heat it to boiling, and then cook it for 10- 15 minutes.
7. Take out the boiled egg, rinse it with clear water, and you can see the beautiful changed egg.
It should be noted that gloves must be worn when making mutant eggs to avoid adverse effects on the skin, and the eggs after use should not be eaten.
