There are different materials you can use to make a flip toy. Here are the basic types of materials
- two sticks (paint stirrers, chop sticks, pencils)
- rubber band
- separator (eraser, foam block)
- hole punch
How to Place a Fulcrum
Awad and Luis begin by connecting the two sticks and separator (in this case, an eraser).
- Place the eraser between the sticks, close to one end (the bottom).
- Hold the sticks and eraser together by a rubber band.
Make a Shape
Awad and Luis make a shape that will rotate as the ends of the sticks are forced apart.
- Cut a shape from cardboard such as a snowman, a rectangle, or an oval.
- Make the shape shorter than the distance from the end of the sticks to the separator. Why?
- Place two holes about 1 cm apart near one end of the figure.
String the Shape
Here is how string the shape.
- Place the shape upside down between the open ends of the sticks.
- Cut two strings about 15 cm long.
- Run a string through each of the holes of the figure.
- Attach one end of the strings near the end of one of the sticks, about 1 cm apart.
- Squeeze the other ends of the sticks together so the ends with the shape are separated.
- Attach the other ends of the strings in similar places on the second stick.
- Make sure the strings are firmly attached to the sticks.
Examples of Flip Toys
Luis and Awad demonstrate different homemade flip toys made with
- paint stirrers and a cardboard shape,
- craft sticks and paper clips,
- a figure connected to the string at two places,
- chop sticks and a round figure that spins.
This is how the flip toy works.
- The flip toy is constructed in the “up position”: the strings are straight across and the flip toy is above the ends of the sticks.
- When the flip toy swings to its down position, the strings cross on both sides of the shape.
- When you squeeze the sticks together it forces the other ends apart.
- When the stick ends are forced apart, they pull the strings straight.
- When the strings are straight across, the shape is forced to the “up position.”
