A Weird and Wondrous Place

Notice the beads in your tub are two different sizes. The balloons are also different sizes. Put the large beads in the smallest balloon. Put a tiny bit of air into the small balloon and tie a knot.

Place the small beads in the large balloon.

Place the small balloon inside the larger balloon and blow it up.

SHAKE IT UP!!!!

HOW COULD THIS BALLOON MODEL AN ATOM? WHAT WOULD REPRESENT THE NUCELUS? WHAT PART WOULD BE AN ELECTRON?

WHAT WAS SHOWN BY THE SHAKING OF THE BALLOON? WHICH MODEL OF THE ATOM IS THIS?
