Minecraft is a game that basicly trolls science, for example:

1. Punch trees with your fists.
2. Build a roof that could float on midair ( no support to roof ).
3. Hold a bucket of hot lava.
4. Random floating pieces of wood.
5. Day is 15 minutes total ( or more or less).

And so on so basicly don't study minecraft for your scool sience tests.
