How it works

How it works

A steam engine works by pressure! A fire heats water to make steam. The steam goes up and into a tube and down into a valve. The steam goes through the Valve and straight to the cylinder. The steam pushes the piston back and forth to make the wheels spin and the steam goes up into the air. And then it starts all over again!

1. Put a balloon over the mouth of a small plastic bottle. The bottle is the cylinder and the balloon is the piston! Make hole in side of the bottle that is the size of a straw.

2. Glue the bottle to a piece of wood with the hole facing to the side.

3. Make a frame of sticks to hold the crankshaft.

4.Cut out a circle of plastic about as big as the top of the bottle and glue it  to a craft stick.

5. Now you glue the other side of the circle to the balloon which is the piston.
