Your own Mango Seed

When you have eaten your mango, don't throw away the stone. It contains a seed, which we try to grow into our own Mango Tree.
Wash and scrub the stone, so it's not so slippery and more easy to handle.
The stone surrounds the seed and is a bit hard. We want to remove it from the hard shell.
I used a metal spatula from the kitchen, You can use anything flat to twist it open. Just don't use a knife to be sure you don't cut yourself or the seed inside.
Be careful when you remove the shell, we want the seed to be intact.
