How do they dispose of egg shells?
It would be a shame to throw it away
Better to stay
Do a super beautiful experiment with your child
see! This is fried with egg shells
The "Diamond Egg" that came out
If you are excited, prepare the materials quickly
Let's make the eggshell turn over!
Glue / hot water / pigment
Alum / pin / egg / dinner plate
-Step 1-
Make two holes at either end of the egg
And blow air into the hole
Blow out the egg mixture
You can also make a scrambled egg with tomatoes
-Step 2-
Use scissors to cut the eggshell along the small hole
Wash the eggshells again
Apply glue and alum to the inside
-Step 3-
Add pigment and alum into the hot water
Stir to make a saturated solution
Immerse the prepared eggshell in the solution
Leave on for 12 hours
-Step 4-
You can choose different colors to do more than a few
-Step 5-
finish! You can take them with you to take pictures!
The principle of this experiment lies in the alum particles inside, its chemical composition is potassium aluminum sulfate dodecahydrate, and its saturated solution is particularly easy to precipitate crystals.
The alum on the eggshell becomes a crystallization center, and the alum particles in the water will continue to combine with the alum on the eggshell to form crystals. Over time, it becomes the eggshell we see like a diamond.
