Hello! I am the Doctor. This is my little place where you can ask me questions and a a tablet or hand draw response! A few rules though.
1.) The bananas are mine. No touchie touchie.
2.) No Posts on Sundays, they are too boring.
3.) Do not let me eat a pear. I hate pears.
4.) Be careful with the TARDIS, she's very special to me.
5.) Weeell. I forgot 5.
Explain the mechanics of the screwdriver.
First of all, sonic equals sound.
It uses sound waves, and spins them fast enough to open a lock, or hack a computer system.
And to make doors stronger, it builds up a wall out of sonic waves that can re-enforce the door.
Does that help Mr. Anonymous?
