Want to try a fun experiment?
Fill a sink partially with cool water.
Get an empty soda can, and put a little water in it. Put it on the burner on the stove and let it heat until the water starts boiling.
Pick the can up with tongs or a heavy glove and put it in the sink mouth down.
You've just made your own mini rail car!
This post is misleading. My mini rail car didn't ride on rails nor did it make choo choo sounds.
A real rail car doesn't make "choo choo" sounds either.
