Coin Funnel a.k.a. Coin Orbitor


You can see at least  one of these coin funnels on various malls, this is so fun for children as it amazes them watching a coin circles around. 
They come in different colors like black, red, blue, and yellow but the most common  is black.

Here is a little experiment for you...

WHICH COIN ROLLS FASTER?
Roll coins on top  of the surface of the funnel. The funnel is a working model of the solar system and displays  Kepler's "laws of planetary motion". This applies to any orbiting body, including satellites orbiting the earth. The center whole represents the sun and a coin rolling represents a planet in motion. Gravitational pull is represented by the downward curve of the surface. The steeper the curve the  greater the pull of the coin , as it gets closer to the center. As the coin circles and descends, its energy of position is replaced by energy of motion.  This is why a planet speeds up  as it nears the sun  and slows down when it's further away.

On this game you can use:
25 centavo coin, one peso coin,five peso coin, and/or ten peso coin and compare which coin rolls faster.
