Suddenly you remember all the things you learned back in school when
you were in the honors class. You tell your friends that is not a safe
place and you must go back home now. You take out a book that reads
"technology in the 21st Century" and go to chapter 5:
instructions on how to use the time machine. You take out a little
square object from your book bacg, push the red bottom and VOILA!!
You and your friends are back home safe.
