Water Marbles

We have made some pretty cool discoveries with these lately.
For instance:

They reverse an image, flip it upside down.

They change size, depending on how long you keep them out of the water.
They bounce.
They don't taste.
They shrink down to the size of a piece of rice if you leave them out of the water overnight, but will swell back up when reconstituted.
You can see right through them, but things look upside down.
