My name is Sivceva Liliana.
My project is called "Beautiful Crystals"
Today I tell you, how to grow a crystalls at home.
First add potassium alum to hot water.
Stir until dissolved
We lower the fishing line into the solution.
And wait for the formation of crystals.
After 30 minutes we have a little crystals.
After 2 hours, our crystal became even bigger than it was.
After 3 hours we got a beautiful crystal.
Then we dissolved in hot water copper sulfate.
This is a solution of copper sulfate.
I learned a lot about crystals.
15. Thank you for your attention.
