Simple, Money-Earning Contraptions in Malls

Whoever put up this contraption in the malls of SM is really smart. I've seen this "science project" in the United States back in the 90's inside theme parks. The idea is to see how fast coins you use for this experiment rolls down the convex-shaped-type of funnel. The answer? Who cares? I just think people are so entertained by this that they don't even know they've been had. Well, not really. You put in the coins and you're not forced to do it.

These things are placed in high traffic areas like cinemas and fastfood areas and the fun doesn't seem to stop for the people. The ones who are really entertained are the kids who are so intrigued by the cause and effect of coins rolling down in a spiral path and into the tube. It's amazing how something like this could earn you big money and the best thing about it is - it works!

Whoever thought about putting this money-earning thing in malls is a genius and I wonder how much they earn from this. For those of us who continue to put money in it - it's literally saying, "It's money down the drain."
