A Steamy Water Mystery

Is that a fog or is it a...ghost? Rubble and the gang are on the case to find out whether that spooky ghost is to blame for the missing yachts at the harbor. Using their knowledge about states of matter, the gang is ready to reveal the solid truth about the gaseous ghost thief!
== Script ==
(We open on a sunny day in Adventure Bay where waves bubbled onto the shore as the gang hung out at the beach)
Danny:Man, my ice pop keeps melting!
Katie:That's no surprise on a hot day like today, ice plus heat equals liquid.
Rubble:Magic!
Ace:It's not magic Rubble. It's simple science. Everything around us is made of matter.
