D.I.Y Craf & Experiment
Monster Automation

With very minimum items, you can create simple machines and also create a really cool art piece!

What you'll need:

- cardboard

- shoe box

- scissors

- skewers (2)

- paper cup (or plastic cup)

- school glue (or hot glue)

- drinking straws (2)

- construction paper

- markers (optional)

- tape (optional)

Use a large plastic cup and trace four circles on the cardboard. Cut the four circles out.

Use school glue to glue two of the circles together to create a thicker cam. For faster results, let an adult apply hot glue.

To make the axle, poke one of the cams with a skewer in the center. Don't worry if it's not quite perfectly centered, it will still work. Apply school glue to attach the skewer. For faster results, let an adult apply hot glue.

With the end of your scissors, poke a hole about an inch in from the top edge of your shoe box. Cut the straw in thirds and poke one piece through the hole.

Tip: Use school or hot glue to secure the straw with the shoe box. The straw allows the skewer to spin freely.

Poke the second skewer through the center of the second cam. Then, use your scissors to poke two more holes through the sides of the box for the straws.

Tip: Make sure the second cam doesn't touch the back side of the box when it is assembled. If it does, poke new holes to move the skewer a bit more forward.

With the cams in place, test out the motion and you will be delighted to discover that rotating the horizontal skewer rotated the vertical skewer!

Use your construction paper and markers to make some monsters! You can also use paper cup to create your monster. Once you are finished, tape or glue it on the vertical axle. Let your monster fly!
