The famous showman P.T. Barnum noticed that people were lingering too long at his exhibits. He posted signs indicating "This Way to the Egress." Not knowing that "Egress" was another word for "Exit," people followed the signs to what they assumed was a fascinating exhibit...and ended up outside.
If, back in the 19th century, Barnum had Google App Inventor, it's a trival problem to solve. Try it out for yourself. Press the button.
This little app, of course, is a) humor (well, kinda) and b) a demonstration of Google App Inventor's power. Enjoy.
